We went to vacation in the Riviera Maya, just south of Cancun. We stayed at the Hotel Excellence Riviera Maya, just outside of Puerto Morelos. I dove 2 days, one just outside of Puerto Morelos, and one from Cancun. Both days included dives to a sunk minesweeper, and a wreck dive. Pictures are up at http://www.flickr.com/photos/chi-diver
