We did last May - same week IIRC. It's a great trip. The crew is a lot of fun, the boat is large and roomy and the food is pretty great also. Ask Stan (the cook) if he's gone diving yet...lol. (he's been on the boat for years and never has)
The diving at French Cay is some of the best I've ever seen in the Caribbean. Sharks, Turtles, Barracuda, Rays a few big Lionfish and healthy Coral all the way down the wall. West Caicos was good also. If you do macro photography some of the coral pillars near the moorings at a couple of the sites are packed with stuff - I spent a couple dives at 30-40' and never made it out to the wall. It was so balmy I slept on the top deck a couple of nights.
