The exception to the above timetable is if you are traveling on Holland America, a Disney Cruise Lines, or a Royal Caribbean Cruise Lines ship. Stuart Cove's Aqua Adventures is contractually bound with HAL to provide diving, snorkeling and SUB experiences; with Disney for 2-tank dives: and with Royal Caribbean for 2-tank dives and SUB experiences to some of their ships when they visit Nassau. If your ship is one that we are contracted to provide services for, the cruise line has arranged for special charter times to make the excursion work. In this situation, you will have to book your excursion directly with the cruise line or once on board the ship. This will ensure the proper pick-ups and services are provided to you.
