Cayman Brac, two thumbs up!

I agree completely!
I've been there 5 times in the past 10 years with groups put together by Superior Expeditions ranging in size from 8 to 30.  It definitely is one of the best places to dive vacation in the Carribean, they have been high in Scuba Diving's readers' choice many times.  We've stayed at Brac Reef and used Reef Divers each time.  I'm love the all-inclusive resort.  Just like the tee shirt, "dive, dive, eat, sleep, dive, eat, sleep,...".    Since they know us well, we usually get a boat to ourselves and hit choice sites all around the island.
