A solo trip to Hawaii is great for everyone. You can meet people or spend time alone on a white sand beach. But you might have questions about how safe it is to travel so far from home by yourself.
Do your research concerning the area where you’ll be staying. Search forums or even call your hotel and ask about the neighborhood at night and transportation in the area. Also, think about how you plan on getting to your hotel from the airport.
Normally when you travel by yourself, it’s recommended that you stay in more populated areas to avoid being isolated, especially at night. But ultimately, this is a personal choice.
