I am staying 3 miles north of town. I was just considering kayaking farther north for safety and I actually just wanted to do some shallow diving up there. The price of private dives sounds reasonable but I plan to be in AC for 9 days and plan to take some regular diving trips, so I don't really want to spent that much for private dives. I was just interested in doing a little diving on my own, but its okay because I am sure the snorkeling is great, so I will just stick to that.
