Cancun

this was about 10 yrs ago... rented a jeep and drove to the mayan ruins and saw some neat stuff, and I would recommend going.. then on the drive back we were skirting the coastline and came upon a little bar on the beach. the bar owner had just caught a nice mahi mahi and invited us to stay for dinner... great time. if you like to "bend the elbow" you can go on a booze cruise too. if you want to scuba dive or snorkel go to Cozumel. if your not certified to scuba dive you have to take a course for like 6 to 8 hours, and those are boring... plus you cannot fly within 24 or 48 hours of scuba diving...
