Do tourists rent a car while there? I know lots of people taking buses but is it common? Before we went to Oahu I read a bunch of stuff online and they were saying how taking the bus is easy and cheap etc... but I decided to rent a car and it was super convenient to drive around Oahu island and see so many more things. I'm just a little skeptical.... I know it will be out of the US so I'm not sure. I found some rental cars for less than $100 for 9 days! that's super cheap. Anyone had experience with renting a car??
