There is no minimum age to visit Royal Caribbean's private island, Perfect Day at CocoCay. It is designed as a family-friendly destination accessible to guests of all ages, from infants to seniors. However, there are age and height restrictions for specific activities on the island. For example, to enter the Thrill Waterpark, there is no age limit, but individual slides have height requirements (typically 48 inches for the larger slides like Daredevil's Peak). The Coco Beach Club is open to all ages, but it requires a paid entry fee for everyone, including children. Regarding supervision, children under the age of 12 must be accompanied by an adult at all times. If you are looking to consume alcohol on the island, the minimum age is 21, regardless of where the cruise ship originated, as the island follows U.S./Bahamian maritime liquor laws. For the "Adventure Ocean" kids' programming on the island, children must typically be at least 3 years old and fully potty-trained.
