Tom / Others: Thinking seriously about Nachi Cocum ourselves for our Cozumel day. Can we walk there from the pier? Has anyone NOT bought the all-inclusive online beforehand, and had luck just walking up and doing the same? That is day 3 out of 3 in a row ports, and we may choose to spend the day on the ship if we're "pooped"....so a bit hesitant to purchase beforehand. Any thoughts? Walk vs taxi, pre-pay vs spontaneous? Thanks!
