Like Rob, blog easily about your life experiences.
I'm thinking of going to San Miguel de Cozumel maybe this October. What are your favorite (not too touristy) things/places to do there for 2-3 days?
As it is a cruise ship port, if it's worth doing, someone has turned it into an attraction (to varying degrees)... but still lots of great places like Punta Sur or Palancar for beaches and swimming, and a lot great snorkel trips (to Columbia Reef and El Cielo) that we really love. You can even snorkel for free on the west side, just on the side of the road. There are some less touristy beaches on the East side (you will need to rent a car or go for a bike ride) but usually, the current is too strong to swim.
