Superclubs' Breezes and Hedonism brands feature included diving. I've had great experiences with diving at Superclubs. I have been able to easily get in 2 dives per day unless they had an extreme number of divers, then they try to make sure everyone gets at least 1 dive per day. All dives are guided with a time limit. First dives is always the shallow dive - 60 ft. If you prove you are a good, safe, smart diver then you can go on the deeper dives - generally 90 ft, but could be deeper if you have an experienced group. The attitude of the diving staff has always been excellent for me.
Couples is an independent all-inclusive resort chain that offers scuba included. I've talked to people who were very happy with diving services at Couples.
Sandals and Beaches are Butch Stewart's all-inclusive resorts that have scuba included. I understand Sandals/Beaches has very strict rules on "pool refresher" requirements and diving frequency limits. The "resort course" for non-certified divers has a fee. It seems to me that their rules try to keep the number of dives per week to a minimum and very, very conservative dive profiles. For the most part you are limited to 1 dive per day. Dives have strict time limits. Only Advanced certified divers are allowed on "deep dives" over 70 feet.
These are not "dive resorts" but rather everyday all-inclusive resorts that include diving. If you want hard-core diving, many dives per day, open limits to your NDL and air consumption, you'll be happier elsewhere. If you want a few dives while on vacation, they are great places. I personally find Hedonism II to be one of the funest places on earth!
