Can someone give me some input on the best excursions for these 3 stops? I have an idea of what I would like to do at each port and I want to make sure I am making the right choices. I would like to see Atlantis in Nassau even though it is $150 pp for the water park & everything included. Is that a fair price? I would like to do the horseback ride and swim at Half Moon Cay. Has anyone here done that before? How was it? I want to snorkel at Grand Turk but Carnival has 3 or 4 different optrions and I am not sure which one to choose. Any help would be greatly appreciated!
