All boat trip diving in Cozumel is drift diving. Drift diving is fabulous, you dont even have to kick. You enter the water and the boat follows the group's bubbles and picks you up at the end of the dive. Visibility is fantastic, water is warm, the reefs are stunningly beautiful. The people are so friendly and most of them speak English. We stayed at Playa Azul Golf and Scuba. All inclusive except for diving but the diving is very reasonable. 2 tank dive was $70. Turtles, Eagle Rays, Parrot Fish and tons of other fish. Most laid back dive trip/vacation I have ever been on. Not to mention they have free unlimited green fees at their Jack Nicklaus designed course for days you dont dive. Bluedreamcozumel,com check it out.
