Our family -- H, W, 19 yo son, 9 yo daughter -- did this tour in June, 2000. We thought it was wonderful. DH and son are great swimmers and took to the water right away. I and daughter are fearful swimmers. So, once everyone else was in, one of the excursion employees asked why we weren't in. I said we didn't understand how to snorkle. Employee said, but do you really want to do it, because if you do, I'll help you. We both said yes. He put on a wet suit, told daughter to stand way back, took me in, had me snorkeling confidently in less than five minutes. Ten minutes later, my daughter was snorkeling confidently as well. Thanks to this wonderful person we all had a great time that day, and we have all snorkeled ever since!
