I dove in play del carmen in feb. Check out the scuba caribe web site.
In playa, every hotel had a dive shop on the beach. the boat picked you up right on the beach and the reef was a 5 min boat ride. By the time your gear was on you could jump, in it was drift diving.
In the lobby of most resorts there are travel agents who can book dive excurtions for you they arange a van and get you to your dive destination be it a cenote or a day trip to cozemel. Any q’s let me know, If you can neg. a price right at the dive shop you may save over using the lobby agents.
