I am a certified diver going on a Princess Cruise that will also allow me 3 half day dives at St. Thomas, St. Kitts and Curacao. The price for the excursions includes all equipment. I have my own equipment and would normally take it but I am interested in opinions of those who have been there before.
I am also a certified diver and I went on a Royal Caribbean cruise in December to dive in warm water for the first time (I live in Oregon). I had a great time. I made all my own arrangements for diving and took all my own gear. I would recommend making your own arrangements too if possible. You usually end up with a better, less crowded dive. If you would like recommendations on who to contact on the 2 islands I dove on that your are going to, e-mail me your interests & questions. I'd be happy to answer them as best as I can.
