If you have already booked with RR, they likely have you assigned to boats for your dives. If you have already received a confirmation email, I would look there for boat assignments and give the office a call to see which sites you are scheduled for (always subject to change given conditions).
Snapper Ledge is always a winner, its a shallow ledge that sits in about 30 feet of water, usually minimal to no current. Lots of marine life, almost always eel and nurse shark sightings.
Pickles Reef is a very shallow reef, but usually has good visibility, and if you are photographer is great based on the amount of natural light. It's also a common spot for the restoration group to do coral outplanting, so you can see some juvenile coral that is beginning to grow.
As mentioned above, Molasses is a great all around reef. There are some ledges in the 30-35 foot range, and with the warmer September water there is the possibility of seeing more pelagic species in the deeper areas. There are plenty of other sites that are relatively shallow coral fingers with sand channels in between. If you've never been, Winch Hole and Hole in the Wall are cool spots.
French Reef is nice because of some of its unique coral structure. There are LOTS of swim throughs, and the coral there is a bit different that the typical "spur and groove" you'll find most of the other places. Visibility and current can be less favorable here than other sites, but still an enjoyable dive.
The wreck of the Benwood is a great wreck if you are looking for abundancy and diversity of fish. It's not so much of a wreck as it is wreckage at this point, and maximum depth is around 35-40 feet. Tons of fish, and almost always turtles hanging out. It is a popular spot for night dives, mainly because of all the turtles that come to rest there.
Personally, Christ Statue, Grecian Rocks, and the northern reefs aren't as great. But that's just my opinion. Hope this helps, and maybe I'll see ya!
