In Grand Cayman you must take a taxi or rent a car at the airport since most hotels are not permitted to offer airport shuttles. Hotel pickup is more readily available on Cayman Brac and Little Cayman, and taxi service and car rentals are also available on the smaller islands as well.
Renting a Car: It's possible to get by without a car on Grand Cayman if you are staying in the Seven Mile Beach area. You could walk or ride a bike. If you want to explore the rest of the island—or if you are staying in a condo—you'll need a car. A car is less of a necessity on Cayman Brac or Little Cayman, but cars are available on both islands. To rent a car, bring your valid driver's license, and the car-rental firm will issue you a temporary permit ($7.50). Rates range from $40 to $85 a day. If you're staying in the Seven Mile Beach area of Grand Cayman, most agencies offer free pickup.
