Oh boy! Here I am a newby on this board and already stirring stuff up like careless finning through a cave. Some welcome! <g> I was just offering an alternative to the question about places to go and the FACT that the boat rides from San Miguel to the dive sites that most divers (certainly first timers) come to Cozumel to dive. What I particularly reacted to in Christi's post was her implication that San Francisco and Yocab are examples of reefs far enough north that it's more difficult for Dive Palancar (or other southern-based operations) to visit than dive operations in or near San Miguel. Sorry, but to use a quote, Christi is "dead wrong," no matter how dives she has under her belt. The Allegro is much closer to those sites and my assertion is easy to prove.
San Francisco, Santa Rosa, La Francesa, and Delilah, which are next to each other, are practically Dive Palancar's House Reefs and are virtually opposite the resort. I particularly know about San Francisco, because it is not one of my favorites, and I'd rather to do repeat dives at the other sites (great shallow dives that provide bountiful photo ops).
Now, if we start talking about the Palancar system, which are must-sees for most first time divers, there is no contest, because those, plus Columbia, Punta Sur and Maracaibo are south of the Allegro, and a really long boat ride from San Miguel.
OTOH, if people are looking for night life, and not into all-inclusives, there is no question that being at a resort near town is an advantage. While the Allegro is far more lively than the Occidental Grand next door, it is still pretty tame by the standards of those looking for Carlos 'n Charlies-type action.
Dive Palancar does one tank dives. The advantage is that some days divers (me) just want to do a couple of shallow dives and maybe a night dive. Also, some people, esp. beginners, just don't like to do deep dives--esp. drifting off the edge of an abyss , but you have no choice on boats that take the longer trips from San Miguel and therefore have to do two tank dives (probably stirred up another hornet's nest there, eh?). However, longer trips to reefs at the southern end of the island like Punta Sur and Maracaibo are by special arrangement, but Allegro's trips are still much, much shorter than traveling from San Miguel.
I have a suggestion that should put this to rest--I hope. One of the books I have on Cozumel, Diving Cozumel, by Steve Rosenberg, can be found at many dive shops and has a map with many of the dive sites Christi listed. Or, pick your favorite alternate. It's easy to check who is right, at least about the reefs that I specifically mentioned.
Finally, I have not dived the northern reefs yet--but would like to. I'll be in Cozumel again Jan 21-28 (sure hoping Wilma misses). It'd be fun to check out some of those spots you talk about, Christie. BTW, if you all like, there is an article I just wrote for the Sacramento Bee on getting into scuba diving that you can check out by logging on to sacbee.com. Just put in the seach word "scuba," and it should direct you to the article--it also links to another article I wrote on abalone diving on the North Coast of California, which I've been doing for forty years. You do have to do a free registration, but it's no big deal. Peace.
