If you're referring to the Cayman Diving Lodge, I give them 2 thumbs up! We dove with operators on 7 Mile Beach for the north and west, but our trips to CDL and East End diving were by far the best. We go back for a week every year. We like to try one or two new destinations every year, but we know we'll always have a great week of diving, friends, good food and relaxing at CDL.
If you're looking for a resort, this won't be the place for you. It's basic accommodations (no tv's, no pool, no luxury), but well kept and clean. The meals are good and the staff (dive and otherwise) are all great.
Enjoy!
