Can anyone tell me who are the current dive ops for Carnival and Royal Caribbean in Roatan, Belize, Cozumel, and Grand Cayman? Yes, I know the ship's dive excursions are more expensive and often not as good as some you can book on your own (at least in my experience), but the last time my wife was in Coz, if she had not been on a ship's excursion she would have missed the boat. So now we have a limiting factor for dives. Any current information is appreciated. Thank you.
