Sorry to post again on this thread but I did remember one thing... When planning our dive trip to Coz in Dec '15 I was watching the prices at the Casa Mexicana hotel for our days through all the various websites. I usually hold off on booking the hotel as sometimes they can offer a last minute deal to fill rooms up to about 60 days out. This year, no such luck and prices started to increase after 60-days out passed and they increased far beyond what our Dive Op (Tres Pelicanos), had locked in for 2015 with the Casa Mexicana. As such, our best deal was found booking our dive/hotel package through Tres Pelicanos. Check with your dive op and see what their dive/hotel/resort packages are running. You know what the diving is going to cost you, you know what the airfare is going to cost you, so compare the "packages" both ways and see if one is less than the other. If your dive op has pre-negotiated prices with a hotel/resort, you may find that to be the best way to go. Remember, peak season lasts a few months and the dive ops who keep a supply of dive visitors coming year-round carry some weight with the hotels and resorts they have teamed up with. They don't necessarily want to piss off a dive op that consistently fills rooms year-round with divers. Anyway, please do let all of us know what decide, where you decide to stay, who you dive with, how you put the best deal together, and how your trip to Coz went!
