I thought I have seen postings where people have done that in the past. or perhaps that was before food was stopped from being taken off the ship?
Darn! I guess the trick will be to eat lunch on board, then get to the beach on our own, and get a cab back after a few hours.
We're supposed to dock in Cozumel at 1:00, so I guess we can just eat lunch around 11:30 or so, and then do the beach break excursion that does NOT include the buffet.
As long as we can get bottled water at Playa del Maya, we should be fine.
Anyone who has done this excursion, they do have bottled water you can buy, right?
