I don't see why you would have a problem. When I went to Thailand we went on a trip to Phi Phi Island. There was scope for everyone to go diving - only with "pipes" and flippers (can't think what it is called) Anyway I was severely seasick. They made me put on a life jacket and more or less thrw me into the ocean. They thought I would recover from the seasickness. What I wanted to do was "just float away". My sisters realised this and kept a tight reign on me. I did get to see all the lovely fish swimming under me though. I reckon you will have a great time.XLeonie
