Cruise lines that operate private islands: Celebrity Cruises, Costa Cruises, Disney Cruise Line, Holland America Line, Princess Cruises and Royal Caribbean International. Disney Cruise Line calls at its private island, Castaway Cay, on itineraries from Port Canaveral.
1 These islands are owned (or leased) and operated by the cruise lines for the exclusive use of their guests.
