Car Rental options are available in a wide range of circumstances from large professional rental businesses all the way to renting a vehicle belonging to the hotel or resort you're staying at. It is always best to review the contract to be sure you understand issues related to insurance, damage considerations, fuel use charges, destination restrictions, pick up and drop off service and possible late return fees.
Many car rental offers can include a driver so if you're not familiar with left-hand driving this can be a worthwhile consideration. Remember, safe driving is no accident.
