Can anyone tell me about the snorkeling in Cozumel? My DH and I are going to do the Clear Kayak and Beach Snorkel while there in December. I have been told that they make you wear a life vest. If you are wearing a life vest how can you go down any depth to really snorkel around the little fishes. I really enjoy snorkeling down below the surface. Do you have to wear the vest? Any comments would be helpful. Thank You
