Intimate Mayan Ruins and Sightseeing Tour, actually. 3-1/2 hours. Small bus - 8 people, thus $85 PP. Worth it, though. San Gervasio was the (modest) ruins. It was OK. Nice drive around the island, especially nice on the east coast! As opposed to my poor review of lots of trash on streets and in Progresso and Merida, Cozumel was VERY clean and well picked up. More so than I remember from other visits.
