Just back from getting my Adv. Open Water certification and diving in Cenote Chac-Mool. Playa is a great place to homebase for diving in numerous cenotes (caverns and caves) and reef diving. There are several dive shops that will package hotels and courses/dives. I used Dive Mex which is in the Villa del Mar hotel on 10th Ave. Dirk, the owner, is a great guy, very quick with email communications, flexible with diving dates and instruction, and the hotel is more like a B&B with safe, clean and comfortable accommodations. Dirk has connections with other dive shops and independent dive guides/instructors so any need you have can be arranged. A great week of various dive adventures that I hope to repeat in the future.
