I went to Cozumel to meet up with an old friend I have not seen in years, and he just started diving again recently. We stayed at Casa Mexicana, and the trip was set up by the dive shop, Tres Pelicanos. The dive operation was very good, and not too expensive. The hotel was fine, although there was some construction going on in the lobby, which bothered some guests whose rooms were closer to the noise. We just dove for three days, and it was excellent. Water was a little choppy at the surface, but other than that, conditions were excellent.
Here are some photos from the trip
