most cabs on property are honest, we have had good experience with all but one, which leads me to advise....
Most fares on property should be around $20 or under...but I clear the estimated fee with the driver BEFORE getting in. Some of them do not like estimating, but that's too bad! We often use cab service for resort to resort transfers, so worth the money, especially when tired! We have had no problem getting a minivan cab for the 5 of us, seems pretty standard there.
Good luck!
