My wife and I went to the Yucatan for our wedding anniversary (14th maybe?). As far as she knows, we went to lounge on the beach at Puerto Morelos, but my ulterior motive was to go dive the cenotes (about a 75 minute drive). The airport locator code for Cancun is CUN. Pick up a car at your agency of choice and hit highway 180D west for 120 miles (197 km) for 2 hours and 17 minutes. It took us over 3 hours, but the road construction apparently has been completed. See, Trump made Mexico pay for something!!!
