Stuart Cove’s is the big dive operation there. It’s a pretty impressive operation on a large scale with multiple boats going out twice a day each. Both they and Bahama Divers will pick you up from the cruise ship for free, and pricing is similar. I have only used SC on my one trip this past August. I would check out both companies websites. From reviews on-line I heard similar stories about both companies being "cattle cars" and limiting bottom time to get more customers into the day. I can say that was the case with SC, but overall it was a fun day of diving. Here is a link to the video I made of our two tank trip: http://www.youtube.com/watch?v=hnjS_qVKdJM
Have fun!
