My husband, 16 month old and I will be staying at the Wailea Marriott 2.13.-2.20.05. All of the comments that we have read swear by the fact that a rental car is a must. We anticipate that the daily cost for the rental, gas, car seat and gas alone will average about $100/day, which is out of our budget, so we are exploring the option of renting a car for a portion (2-3 days) of our stay. Round trip transfers are included in our package so arrival and departure will not be an issue with respect to ground transport. It would be helpful to know if there are any local agencies which we could use vs the agencies at/near the airport. Has anyone reading done this?
