I could not praise these folks enough. I dove with these folks last January. They do everything for you except breath. I was lucky enough to have the same DM on most of my dives and I think he was the best DM I ever dove with. Stefeno
If you take you own gear they will provide a locker at the dive shop. This way you will not have to lug it back and forth from your room. My room was pretty close to the dive shop so I took my regs and computer and mask back to my room to soak in the tub each day. They have trips to coz and they have Cenote trips. That is besides the reefs that are right in front of the hotel. The Cenotes are only a couple minutes away.
When you arrive you sign all the paperwork and leave your C-card with them in your folder. Everytime you want to dive or purchase something from the dive shop you just sign for it. At the end of the week you settle up with the shop and get your C-card back. The more dives you do...the cheaper the dives become. With this way of doing it....you do not have to decide and pay for a certain package at the beginning of the week. If you have any more questions just give a shout.
Make sure you take mosquito repellent and a treatment for chiggers. ( we were told by a pharmacist to use lice shampoo at 100% strength for 15 to 20 min on the effected area) seems to work.
If you like any type of snorkeling you must take a cab to Akumel and go to the Yal-Ku Lagoon. It costs $5usd for a wrist band and you can come and go as you please. The lagoon is fresh water in the back and salt out near the sea. %100 natural habitat. Fantastic. Have the hotel pack you a luch of just make one up for yourself at the buffet.
