I may've just glossed over this, but what place did you stay at? What did you think of it, and the surroundings (e.g.: walking distance restaurants)?

I stayed at Casa Mexicana, which seems to be the most popular choice for divers and could thus make it a good place to stay in order to network with other divers, perhaps at the free breakfast. The location was very convenient, and the quality of the accommodations and the service pleasantly surprised me. It was more than adequate for my purposes.
There were plenty of restaurants along the waterfront/Rafael Melgar Avenue. I just walked along it until I found a place to eat. The food was good and reasonably priced, and I did not get sick.
From other threads, it's been indicted Aldora ends dives as a group rather than sending up low air/nitrox divers in buddy pairs, based on the belief this is a safer practice. People vary in whether they agree with that policy. Hence we have a choice when we dive travel...
Richard.
The Aldora DM initially had me surface by myself on many occasions, so that the other divers could continue to dive their tanks/computers. This included one occasion when I had a positive buoyancy problem that the resulted from the DM's underweighting of me to compensate for the greater weight of the steel 120s. I could have used some help in that situation, or at least some extra lead, but I had to surface alone anyway. Then they changed and had us surface as a group when others were low on air, even when I still had enough air to continue to dive my tank/computer for a while. So their policy on this issue was not consistent, and the inconsistency worked to my disadvantage, i.e. I did not get to dive my tank once I had reduced my air consumption.
"The DM once aborted a dive for the whole group less than halfway through because one diver's computer malfunctioned. I do not know why he could not have surfaced alone or with a buddy and allowed the rest of us to continue the dive." I would never send anybody to the surface alone if I was a dive master. I am sure the original poster would figure out why. In the last year there have been incidents on the island that surfacing without a buddy has become an issue. As for bringing the group up because of a bad computer, that is a decision he made and I am sure he lost favor and tips because of it. It could easily have been avoided if the briefing before the dives included what to do with failed equipment.
I had gotten the impression from my pre-trip research that surfacing alone is a frequent or common practice in Cozumel, but not universal. (Cozumel veterans, please correct me if I am wrong). I had thus prepared for the possibility of surfacing alone, even though I had never done it before, as I figured it was worth expanding my skills and experience.
Were the incidents on Cozumel that resulted from surfacing alone due to issues with the boat captains not being able to find people after they had surfaced? Speaking from my own and admittedly limited experience there, the boat captains at all of the operators with which I dove were consistently able to find us quickly when we surfaced. Their ability to follow our bubbles and see our buoys from a distance so consistently impressed me. I never had to wait more than a minute or two for them to pick me or us up. The DMs also made sure that we knew the names of our boats so that we could have another boat contact them by radio if they were not nearby and another boat was nearby. I could imagine that it might be a problem, though, if you surfaced at a remote site with less boat traffic and no other boats were nearby.
