We are going to be at CSS next month. After much deliberation I decided that I would like to try SCUBA and see if that's for me. I read that there are intro classes in the main pool and one complimentary dive per visit. Has anyone done the pool class? How long is it and how informative? What about the intro dive? I was talking to a PADI certified diver friend who told me that it is never more than 30 feet. Has anyone done it? What was it like?
