If you are afraid because you don't like water don't worry too much. I don't swim and I don't like to go under but I was O.K. I did all the slides, C&G included. I went under every time but it's not too hard to get up. DH always went down first so he could help me get up quick before I panicked. There lifegaurds everywhere too. If a forty-something old big scaredy cat like me can do it anyone can.
