Husband, 18 yo daughter, and myself arranged a private car and driver for our port day in Cozumel. Sergio (Tours Plaza) was waiting as we walked off the ship. He had our paperwork, which gave us peace of mind that we found the correct person. He was courteous, and very informative about the island. He was fun to be around. He drove us around to the things we wanted to see, as well as offering up additional suggestions. We started with a tour of the town, then we saw the San Gervasio Ruins, did a tequila tasting (much fun), drove the east side of the island for scenery, stopped at Chankanaab to snorkel (spent about 2 hours there), then he took us to a restaurant in town as my husband wanted to experience a 'real' restaurant, not touristy. He also drove us by some shops away from the port to find souvenirs. We were with him about 6-7 hours. The van was clean and had air conditioning! Was a great day, away from the crowded tour buses the ship excursions offered.
