We are the grandparents -- we are much older physically, even if young at heart. . Cocobay will be great for our children and some of our grandchildren. We, and two young grandchildren, would be better off if we could simply go from the ship to the beach at Cocobay and build a sand castle and take a swim and return to the ship within about two hours and bathe and rest. Is this possible? Do you walk from the ship to the island or what transport do you use?
