Quick Facts You Need to Know:
- Book your rental car THE SAME DAY you book flights (not kidding)
- Kona airport = most expensive car rentals in the entire US at $127/day average
- 2026 is weird: fewer tourists but prices staying sky-high
- New Green Fee tax starts Jan 1, 2026 (adds to your total trip cost)
- Discount Hawaii Car Rental consistently beats booking direct with rental companies
- Your credit card probably already covers rental insurance (check before you fly)
I’m going to be honest with you. I’ve been visiting Hawaii since I was 10 years old. Over 40 trips. And I’ve made every single car rental mistake you can possibly make.
I once showed up in Kona without a reservation during Christmas week.
Want to know what I paid? $400 per day for a basic sedan. FOUR HUNDRED DOLLARS. For a week, that’s almost three grand just for the car.
Never. Again.
Here’s what nobody tells you: your rental car will probably be the second biggest expense of your entire Hawaii trip, right behind your hotel.
And if you screw it up (which is so easy to do), it can completely wreck your vacation budget.
Stop Reading This and Book Your Car Right Now
Seriously. If you already have Hawaii flights booked but no rental car, stop what you’re doing and handle that now.
The Hawaii rental car situation is completely different than it was before 2020.
When COVID hit, rental companies panicked and sold off huge portions of their fleets. They never bought them back.
And even though Hawaii is actually expecting about 5% fewer visitors in 2026, rental car prices are NOT coming down.
Why? Because there aren’t enough cars. Simple supply and demand.
Back in 2019, you could find rental cars for $50 a day pretty easily. Those days are gone.
In 2025, rental cars in Hawaii averaged $67/day, but that number is misleading because it doesn’t account for peak season pricing.
During summer and holidays, I’m seeing rates of $200-$300 per day regularly. And during Christmas week 2025? Some families were quoted $600 PER DAY.
The worst part isn’t even the price. It’s arriving in Hawaii with no rental car available at all. Period.
I’ve heard from families who had to completely change their plans because they waited too long and every single rental company was sold out.
Here’s What Actually Works (from Someone Who Books Hawaii Trips Constantly)
Book your car the minute you book your flights. I don’t care if your trip is 8 months away. Do it.
I use Discount Hawaii Car Rental for every single trip now.
They work with all the major companies (Alamo, Enterprise, Budget, Dollar, Avis, Thrifty, Payless) and somehow consistently get better rates than booking directly with those same companies.
I don’t fully understand how they do it, but I’m not complaining.
The part I love: no booking fees, no prepayment, free cancellations.
This means you can book a car RIGHT NOW to secure it, then keep checking prices over the next few months.
If the rate drops, cancel and rebook. I’ve saved hundreds of dollars doing this.
They also include two free extra drivers automatically (most companies charge $10-15/day per extra driver).
And if you’re traveling with someone aged 20-24, they only charge $8/day for young drivers instead of the typical $25-35/day that rental companies hit you with at the counter.
Check current rates here and thank me later.
2026 is Going to Be Weird (And Expensive)
Okay, so here’s what’s happening with Hawaii travel in 2026, and it’s honestly kind of bizarre.
Fewer people are visiting Hawaii. The University of Hawaii economists are predicting visitor arrivals will drop about 5% in 2026. You’d think that means cheaper prices, right?
Wrong.
Prices are staying high or even going UP because the visitors who ARE coming are spending more per trip. The rental car companies know this. Hotels know this. Everyone knows this.
Plus, starting January 1, 2026, Hawaii added a new “Green Fee” tax of 0.75% to all lodging. So your total trip cost just went up even if individual rental car rates stayed the same.
And here’s the really weird part: each island is behaving totally differently right now. Maui and Oahu don’t follow the same patterns anymore.
Some weeks you’ll find availability that never existed before (people have been booking Mama’s Fish House reservations that were impossible to get for years). Other weeks, everything sells out faster than ever.
It’s unpredictable in a way it hasn’t been in the past.
Real Hawaii Rental Car Costs in 2026
Let me give you the actual numbers so you can budget properly. These are REAL prices I’ve tracked:
By Season (Average Daily Rate):
- January: $49/day (cheapest month)
- Summer peak: $90-$196/day
- November: $78-$196/day (why is November so expensive? Nobody really knows)
- Holiday weeks: $200-$600/day (yes, seriously)
By Island (What You’ll Actually Pay for a Week):
- Honolulu: $248-$316/week
- Kauai: $254-$474/week (huge range depending on timing)
- Maui: $258-$688/week
- Big Island (Kona): $264-$343/week – currently THE most expensive airport in America
- Big Island (Hilo): $247-$258/week (fly into Hilo if you can, it’s cheaper)
By Car Type:
- Compact: $55/day
- Midsize: $60/day
- SUV: $67/day
- Large car: $78/day (sometimes cheaper than compacts because of weird demand)
- Convertible: $87/day
- Minivan: $175/week minimum, often way more
What to Expect in 2026
Industry experts are saying Hawaii rental car prices will stay elevated or go up in 2026. Here’s why:
Rental companies learned their lesson during the pandemic. They’re keeping their fleets smaller to protect profit margins. It’s more profitable to rent fewer cars at higher prices than to have a bunch of cars sitting around.
They’re also doing dynamic pricing now (like airlines have done forever). Prices can change multiple times PER DAY based on real-time demand. I’ve watched prices jump $30 between morning and afternoon while researching for clients.
The state of Hawaii is also dealing with a mild recession and policy uncertainty around tariffs, which is making everything more expensive across the board.
Look, I wish I had better news. But if you’re planning a 2026 Hawaii trip, don’t expect car rental prices to magically drop. If anything, book earlier than you think you need to.
Don’t Get Scammed at the Rental Counter (Insurance Edition)
This is where I see families waste SO much money. The rental counter insurance push is aggressive. Like, really aggressive.
When you pick up your car, they’ll start listing off insurance options:
- Collision Damage Waiver
- Loss Damage Waiver
- Supplemental Liability
- Personal Accident Insurance
- Personal Effects Coverage.
It sounds important and scary and official.
It can add $30-50 PER DAY to your rental. For a week, that’s an extra $210-$350.
Here’s what I do BEFORE I even book my flights:
I call my credit card company. Most premium credit cards (like Chase Sapphire, many American Express cards, etc.) offer excellent collision and theft coverage when you use that card to pay for the rental.
I also call my personal car insurance company and ask if my policy extends to rental cars. Many do.
If you’re already covered by your credit card or personal insurance, you can decline the rental company’s insurance.
Just make sure you have documentation handy because rental agents can be really pushy. Some will act like you’re making a huge mistake. You’re not.
The One Big Exception
If you’re driving the Road to Hana or exploring remote Big Island beaches, read your insurance fine print super carefully.
A lot of policies specifically EXCLUDE unpaved roads. And guess what? Some of Hawaii’s most beautiful spots require driving on dirt roads.
I learned this the hard way when my credit card company told me after the fact that they wouldn’t have covered damage on the unpaved section of the Road to Hana.
Thankfully nothing happened, but it was a wake-up call.
If your policy excludes unpaved roads and you’re definitely doing the Road to Hana or South Point or other dirt road adventures, you might want the rental company’s insurance for those specific days.
Want to know if you even need a rental car for your trip? I cover this in detail on my podcast: Hawaii Travel Tips: Do You Need to Rent a Car? Complete Guide.
Picking the Right Car Size (Without Overthinking It)
People stress about this way too much.
I see two mistakes constantly: families who rent a compact car to save money and then spend their entire trip miserable and cramped, OR people who rent a massive SUV they don’t need and struggle with tight parking at every beach.
Here’s my actual advice as a Hawaii travel expert and someone who’s rented pretty much every car size available:
If you’re staying in Waikiki for a beach vacation: Get a compact or midsize. Parking is ridiculously tight. Gas is expensive ($4.50-$5.50/gallon). You’re not hauling tons of gear around. A smaller car just makes sense.
If you’re doing the Road to Hana or exploring remote Big Island beaches: You want decent clearance and space for coolers, beach gear, possibly muddy/sandy stuff. A midsize SUV makes sense.
Listen to my podcast episode about the Road to Hana before you go: What You Need to Know About the Road to Hana on Maui.
Seriously, it’ll save you from making mistakes I see families make constantly.
If you’re traveling with kids: Count your suitcases, car seats, strollers, beach gear, and snorkel equipment. Then add 20% more space than you think you need because kids’ stuff expands like magic.
The Weird Pricing Thing Nobody Talks About
Here’s something bizarre about Hawaii rental car pricing: larger cars are sometimes CHEAPER than smaller ones.
I know it doesn’t make sense. But demand drives pricing, not logic. I’ve booked full-size sedans for less than compact cars multiple times. Last year on Maui, a large car was $15/day cheaper than a compact for the same dates.
Always compare prices across different car sizes. Don’t just assume smaller = cheaper.
What Different Rental Companies Actually Charge
Every rental company has different policies and fees. After renting from basically all of them over the years, here’s what you need to know:
| Policy | What’s Standard | What to Watch For |
|---|---|---|
| Fuel Policy | Full-to-full (return with full tank) | Some companies offer prepaid fuel at inflated rates. Skip this. Fill up yourself near the airport. There’s usually a Costco gas station nearby with cheaper prices. |
| Extra Driver Fees | $10-15/day per driver | Spouses are usually free. Discount Hawaii Car Rental includes TWO free extra drivers automatically, which is huge. |
| Young Driver Fees (21-24) | $25-35/day | This adds up SO fast. Discount Hawaii Car Rental only charges $8/day for young drivers. That’s $17-27/day in savings. |
| Minimum Age | 21 years old | Under 25? You’ll pay more AND have limited vehicle selection. It’s annoying but it’s everywhere. |
| Damage Documentation | Pre-existing damage should be noted | ALWAYS take photos/video of the entire car before you leave. I take at least 20 photos on my phone – every angle, underneath, the roof, inside. Takes 3 minutes and has saved me twice from bogus damage claims. |
| Mileage | Unlimited | Hawaii islands are small so this isn’t usually a concern, but confirm anyway. I’ve never hit a mileage limit in Hawaii. |
| Return Time | 24-hour periods, not calendar days | Pick up at 2pm Tuesday? You need to return by 2pm Wednesday or you’re charged another full day. Set a phone alarm. |
| Cancellation | Varies wildly | Discount Hawaii Car Rental offers free cancellation, which is perfect for monitoring prices and rebooking if rates drop. |
The Parking Situation (aka Another Hidden Cost)
Oh, and speaking of costs nobody tells you about: parking.
Most Waikiki hotels charge $40-$60 PER DAY for parking. That’s another $280-$420 for a week. I’ve seen families completely blindsided by this.
Factor parking into your budget BEFORE you book your hotel. Sometimes a hotel that looks more expensive actually saves you money when you add up parking costs.
I specifically look for hotels with free or discounted parking when I’m researching where to stay. It makes a huge difference in your total cost.
Popular beaches and hiking trails are another parking nightmare. Parking lots fill up by 8-9am at places like Hanauma Bay on Oahu or certain Big Island beaches. You need to either arrive super early or have a backup plan.
And street parking in residential areas near beaches? Be really careful.
Many neighborhoods have residential-only parking, and they WILL ticket you. I learned this the expensive way in Kailua.
Ask locals or read parking signs very carefully before you park.
Should You Rent an Electric Vehicle?
Maybe? It depends.
Hawaii has a decent EV charging network now, especially on Oahu and Maui. If you’re staying mostly around resort areas and not doing super long drives, an EV can save you money on gas (which is $4.50-$5.50/gallon).
But charging takes time. Time you probably don’t want to spend on vacation sitting at a ChargePoint station.
And if you’re planning remote adventures (South Point on the Big Island, backside of Haleakala, etc.), charging stations are basically nonexistent.
My take: I’d consider an EV for an Oahu trip where I’m staying in Waikiki and just doing day trips. I wouldn’t rent one for exploring the entire Big Island or doing the Road to Hana.
Feeling Overwhelmed? I Get It
Planning a Hawaii vacation is exciting but also kind of stressful. Flights, hotels, rental cars, activities, figuring out which island to even visit. It’s a lot.
I’ve been that person standing in the Target parking lot at 10pm, stressed about whether I booked everything correctly, wondering if I’m forgetting something important.
If the car rental thing (or honestly any part of planning your trip) is making you anxious, I offer personalized Hawaii travel consultations.
As a certified Hawaii Destination Specialist and self-proclaimed professional tourist who’s made 40+ trips to these islands, I can help you figure out exactly what you need, where to actually save money, and how to avoid the mistakes I see families make constantly.
Sometimes you just need someone who’s done this a million times to tell you “yes, that’s the right call” or “no, skip that, it’s not worth it.”

Your Actual Game Plan
Okay, here’s what you need to do:
Book your rental car through Discount Hawaii Car Rental as soon as you book your flights.
Check your credit card and personal auto insurance coverage BEFORE you get to the rental counter.
Choose a car size that actually makes sense for your plans. Factor parking costs into your budget from the start.
And look, Hawaii is expensive. There’s no way around that. But it’s so worth it when you plan smart.
The freedom of having your own car means you can explore hidden beaches, stop at roadside fruit stands, chase waterfalls, leave when you want, stay as long as you want.
Those unexpected detours and spontaneous stops? That’s where the magic happens on Hawaii trips.
Don’t let the rental car piece stress you out or blow your budget. Now you know how to handle it.
Questions People Actually Ask Me About Hawaii Car Rentals
How much does it cost to rent a car in Hawaii?
Way more than it should, honestly. The average in 2025 was around $67/day, but that doesn’t tell the real story. In January, you might find cars for $49/day.
During summer or holidays? Try $200-$600/day.
Kona airport is literally the most expensive place to rent a car in the entire United States right now at $127/day average. Budget at least $300-500 for a week-long rental and you won’t be shocked.
Do I actually need a rental car in Hawaii?
Depends on your island and what you’re doing. Staying in Waikiki and just hitting the beach? You can probably manage with Ubers, though it gets expensive fast.
But on Maui, Kauai, or the Big Island? You absolutely need a car unless you’re literally never leaving your resort. Public transportation is pretty limited on most islands.
Listen to my podcast episode Do You Need to Rent a Car? where I break this down by island.
When’s the cheapest time to rent a car in Hawaii?
January and September are usually your best bets. January averages around $49/day. But here’s the thing: even if you’re traveling during “cheap” months, you still need to book EARLY.
Prices jump as your rental date gets closer regardless of season. I’ve seen January rates triple when people waited until 2 weeks before their trip.
Should I buy the rental car insurance?
Probably not. Most premium credit cards cover rental cars (call yours to confirm). Your personal auto insurance might too.
The rental company insurance is like $30-50/day extra, which is $210-350 for a week. That’s real money.
But there’s a catch: if you’re driving unpaved roads (Road to Hana, South Point, etc.), your coverage might not apply. Read the fine print or call your insurance company before you decline coverage.
Can I rent a car if I’m under 25?
Yes, starting at age 21, but they’re going to charge you extra. Most companies hit you with $25-35/day in young driver fees. Over a week, that’s $175-245 just for being young, which is ridiculous.
Discount Hawaii Car Rental only charges $8/day for drivers 21-24, which saves you a ton.
Which Hawaiian island has the cheapest car rentals?
It changes constantly. Right now Hilo on the Big Island and Honolulu tend to be cheapest. Kona and Kauai are usually most expensive. But these rankings shift week to week based on demand.
Always compare all the islands through Discount Hawaii Car Rental because sometimes an island you weren’t even considering has way better car rental prices.
What size car should I get?
For couples or solo travelers, midsize works great. Families need a midsize SUV minimum, especially if you’re doing beach days with all the gear. Groups of 5 or more, get a minivan.
And here’s a weird trick: sometimes larger cars are CHEAPER than smaller ones because of how demand works. Last trip to Maui, a full-size was $15/day less than a compact. Always compare all the sizes.
Are rental car prices going to drop in 2026?
Nope. Sorry. Even though Hawaii is expecting fewer tourists in 2026, prices are staying high because rental companies are keeping their fleets small and using dynamic pricing.
Plus there’s a new Green Fee tax starting January 1, 2026 that adds 0.75% to lodging costs. Everything is getting more expensive, not less. Book early and hope for the best.
