Thanks for sharing your beautiful pictures. The water in Grand Cayman is so crystal clear. I loved our cruises to the Caribbean and Southern Caribbean. We cruised RCL and Celebrity (our favorite of the two). I love the water and love to snorkel. But I must admit I can go under the water with my snorkel mouth piece, I tend to swallow water! I did do the Snuba in Aruba which was fun using a regulator attached to the tanks sitting in the boat on top of the water. You only go down about 30 feet but it worked for me. How I wish we could do this again but as we can't thank you so much for sharing.
