Cozumel, Mexico help!

[Adam6521]

We are going to Cozumel in the middle of September as long as hurrican season does not get in the way.  I have been their once and stayed close to town.  Now we are going to stay at El Cozmuleno Resort.  This is north of the airport.  Also right infront on the Country Club Golf Course.  There is not to many dive sites on the North end were we are going to be staying.  We will drive south of town to get to the dive shop I have dove with in the past.  Wondering about the current on the North West part of island.  Must be fairly strong.  Also any other info and tips you can give us would be great.  I know many shops wont drive that far to get you.  Also we have to see how far south the northern dive shops go.  She has no ocean diving experience so we need to do a beach dive to get her accustomed to it.  Any thing at all will be helpful thankst.
