When we booked this tour, my husband VERY reluctantly agreed. He had never snorkeled before and was basically sick with apprehension all day long... like not even a smile as we boated out to the sight. I admit I was nervous too. What if one of the giant manta rays wrapped itself around our legs and drug us deep into the ocean? And, hello? Sharks? Now I feel absolutely ridiculous for thinking such things. We were uneducated, but Drew and Sam explained everything in a fun and genuine way. We knew we were in good hands. They talked to us (by name!) while we were in the water, and they were having just as much fun as we were. We are not thrill-seekers. We're middle aged desert dwellers, and we almost let fear allow us to miss out on this beautiful, once in a lifetime experience. Don't make that mistake. As much as the rays almost stole the show, Sam, Drew and Captain Dan are the real stars because they made it happen for us. I can't recommend this enough.
