That's our go-to place, as well. It generally only includes two meals, so we don't feel guilty doing our evening meals elsewhere for some variety.Scuba Club Cozumel. Easiest in town including food and diving. Really easy peasy. And on frugal side too. Check their pricing.
I did the dive portion of my AOW there on our last trip. On an earlier trip, my daughter (eligible for a referral for OW dives wasn't yet comfortable enough for her, my, or her US instructor to suggest she should just hop off a boat Cozumel-style. So we bought the Discover Scuba package and she had a divemaster assigned to her - last off the boat so she could take her time. I got to dive with her, which was a hoot!
I've enjoyed all the diving I've done with them. BUT - their standard package caters to the easier end of diving - so if you want lots of adventure (rather than great - but relatively lazy drift diving), another dive shop might be better to customize your experience.
