I'm very shortly going on a trip to Caribien with Royal Caribien Cruise Line, we have the following port of calls:
San Juan, Puerto Rico
Charlotte Amalie, St. Thomas
St. Croix U.S.V.I
Basseterre, St. Kitts
Roseau, Dominica
Bridgetown, Barbados

Does anyone have experience with diving resorts in any of these places? I'm looking for a place where I can come early in the morning and hire scuba gear and get a couple of dive and return to join up with the family approximately 4 hours later. Need a place where I can either make arrangement by phone or internett or just drop inn, as we are only staying in each location for 12h.

I'm looking into buying a Canon 7D. I have read a lot of tests, reviews and such of the camera. What I haven't found is good tests, reviews and comparison of the various uw-housing choices. Do anyone know of tests or comparison between the uw-houses for 7D or could give me a rundown of the major drawbacks and benefits of the houses?
