I have been intrigued by Scuba Club Coz for many years, but I have never stayed there. My wife and I enjoy good (quiet) air conditioning, hot showers and reasonably soft beds and pillows. We don't ask for fancy; just clean, cool and decent television.
How do the rooms at SCC rate as compared to Hotel Cozumel or similar mid range hotels? I'm convinced that the diving, social life and food are good based on many reviews on the ScubaBoard. Honestly, the rooms at Hotel Cozumel are sort of hit and miss when it comes to quality.

The beds are futons, or the equivalent, as seems to be relatively standard in Cozumel. If you like sleeping on futons, they are fantastic. If you don't - you probably won't be happy. (FWIW, that seems to be standard - I have seen complaints that the beds are hard in reviews of several Cozumel hotels.)
We had no problem with room temperature - but I do not recall whether the air conditioning was quiet, or not. It certainly wasn't noisy enough to bother us. No TV in the room - although I did not notice its absence until someone pointed it out upthread (18 months or so after I visited there). I don't recall if it had television elsewhere on the premises or not.
Showers were hot.
