I haven't found much on the scuba diving. We are staying at the Carlyle in July and wanted to try scuba diving. Is there much to look at? Is it worth the money to take the course or just go snorkeling? We don't plan to stay at the Carlyle much, plan to go to the other resorts, is there a place to shower and change at the other Mobay resorts before dinner? Any info is really helpful as this is our first all inclusive trip.
