Hi Ivorypen

you sound a lot like me. My husband and I have been coming to the island every year since 1993. Never once has my head gone under the water. I too like to be able to stand in water and keep my head out. I found that taking one of the life jackets and putting it around my waist helps a lot. And a lot of the tour guides will stay with you and also have a ring you can hold onto. They keep saying you can't sink in saltwater but I don't want to take a chance. Plus the water is very shallow by the beach. You can walk a long ways out.
