Being the selfish type of person may I please add Cozumel Island to the sites you'd enjoy seeing and also feel free to contact me ahead of time and we'll put something together for a tour of our 30 mile long Island.Every tour here is different and I wouldn't mind picking you up at our ferry that you'll more than likely be arriving on from Cancun-if leaving from there.The other sites you've written down all look good,it's also great to be able to do some homework early.Be hearing your up-dates.July1@czmx.com
