we rented a car and then went to Aquatica, Seaworld's new water park..awesome.
No cruises added
we took the public bus #10 to cable beach, a free beach with 5 star hotels on it..cost $1.25 per person one way..
we booked through the cruise line a sail and snorkel, perfect..
completely beautiful..the crew even brought the buffet to the island..awesomeeeee..
the ultimate island experience had it all. A must do if you have never been
