Dawnskers: I'm wondering what certification level you guys have and how comfortable you are diving deep. The Blue Hole dive is to at least 130 feet and involves a decompression stop. If you are used to diving once or twice a year to 60'or so in clear warm waters, on your basic OW cert, maybe you shouldn't dive the Blue Hole. There are still some excellent dive days you can do without taking on a more advanced dive. Turneffe, Halfmoon Caye, etc. If you have your heart set on diving the Hole, be sure to do a number of other area dives in the days preceeding, just to ensure you are again comfortable with your skills and your gear etc. Maybe I'll run into you in San Pedro, I arrive on the 14th.
