I think there are several issues at play. 1. Divers are going during "Norte" season....sometimes, just like baseball...you get hit with a weather delay. 2. Apparently there is a new harbor master who may be pulling the trigger a little quick. When he does, the dive operators show up and if it is still safe to go, he seems to listen. I think there is a learning curve, and maybe some local politics involved. 3. When the port is closed, the larger boats can usually go out. Aldora has a larger boat ( I think the Felicity) that can still run and they will go to the other side of the island to dive. It matters who you dive with. 4. The other events are discoverable with a little searching or at least checking with your preferred dive op and to some degree can be planned around.In 10 years, we have been hit with a port closure 1 time. Just this year, American Airlines has horribly screwed up our travel plans on 3 out of 4 flights. I absolutely share your concerns since my time away from the real world is very limited. Between work and cattle, "Norte" season is the primary time I get to go. I'm in Cozumel to dive, everything else is just an awesome fringe benefit. Port closures worry me, and I watch the weather and wind reports for 10 days or so before we leave, but the airlines are far more likely to take a diving day away than a Norte.For the diving, price, food, people, ease of travel, knowledge of the island, familiarity of dive ops, it's still Coz for me! See you there!!!!! (hopefully January)Jay
