My boat is stored in Cozumel. What are some fun things to do there? Snorkeling I’ve been there before, so I do not need. Is there a tour that is only good or shop in town?

I ‘ m that goes in a passage to Cozumel, Mexico and Key West, Florida. I will be only in any place by near 9 hours every day. Which are some things of the diversion to see and do in these two places? I hear that it ‘ s really beauitful in Cozumel, so I ‘ m that takes definitively my camera!
