Whether we stayed on the island or visited by cruise ship, we found so many things to do in Grand Cayman. On a stay at the Ritz-Carlton Grand Cayman for 16 days, we enjoyed a great luxury resort vacation. And the chance to explore the island above and below the water. On cruise ship visits, we spent time in the main port in Georgetown and took in some of the water fun.
If you want to visit without a car, there is a ferry that travels between Camana Bay and Rum Point. A great option of you want to head out to Rum Point for dinner and a sunset one night.
