Thanks for the feedback. Have gone to St John's for the last two January vacations. Great campground on Cinnamon Beach, but it's about $90 a night for a big tent with cots, whereas it seems I can stay in a hotel room on AC for less than half of that. I've heard that the water is not as clear on the beach in AC until you get out further, but that the snorkeling is more varied than in St John. Can't wait to check it out.
