But Hawaii is a place where shoes are optional, and you have the option of getting a little zany on the choice of transportation. You can try a scooter, limo, Jeep, luxury Italian sedan, or an old beater surfmobile. Or fool them all, and use the bus and a bicycle to get around.
Kauai has some excellent coastal bike paths. The Big Island invites mountain bikers who want to get way away from it all. Oahu has excellent public transportation and having a car in Waikiki can be more trouble than it's worth. Daily hotel parking fees can be a costly add-on. On Maui ... a car is your best bet.
