My boyfriend and I are taking our first real vacation that does not include visiting family or friends and will be staying at CNA in Nov. We are very excited but I am a little worried about the Scuba diving. Chris normally never goes in the water and says he can swim but is not that strong. He wants to try the snorkeling and scuba diving while we are there. We are not going to get certified but still want to try it out. What do we need to know or do in order to do this trip... I read somewhere that we would have to be able to swim 8 laps in the pool? I'm not sure if I am in shape enough to do this now myself lol.. Could you please help so that we can prepare.
