There are some things we want to do in Cozumel while we are so close, and it's going to mean spending two pretty full days and one overnight away from TTR. We're planning on taking the ferry over on the morning of September 8th, diving all day with Dive with Martin, spending the night at a very good rated hotel in town, having dinner and drinks locally in Cozumel, and then doing an all-day jeep tour the next day. We'll ferry back and be back at TTR sometime Thursday in the early evening, I would guess. Anyone who might have similar interests is welcome to come along!
