Renting a car is the best way to get around each island. While O'ahu has a good bus system, service is limited on the other islands, and it would be difficult to get to certain scenic points without a car. Enterprise gives Hostel Tours Hawaii customers discounted rates & reliable cars. Plus, if you rent for 5 days, you get 2 extra days for the same price!

Select these locations:
O'ahu- Honolulu (If you dont want a car for the whole time on this island, select the SEASIDE or KALAKAUA locations, which are in Waikiki, very close to the hostel, or they will even pick you up)

Maui- Kahului (airport)
Kauai- Lihue (airport)
Hawaii- Kona or Hilo (airport)
