First Dive? going to Cozumel

[mc-cro]

Just found out Im going to Cozumel in January for sales meetings.
gonna be there for about 10 days. I have already been snorkling in Cabo, Grand Caymen, Bahamma's, and Cozumel, however I would really like to do some DIVING on the reefs this year. Should I take classes before I get there? or just go, take a quick class there and rent some gear and jump in the water?

I was told there are a couple of sites that are only like 25ft and you do not need any type of certification, they just let you go. apparently at 25 ft, if youget in trouble, youcan just drop the belt and go to the surface.
