Cancun or Cancun airport? If you're arriving at the airport don't go to Cancun to catch the bus...you're going the wrong way. Catch a shuttle to Tulun or Playa del Carmen and get the primo bus to Chetumal.
Good Luck...I'm going the same way next Sept. to Caye Caulker.
Thanks, I'm flying into Cancun Airport, but staying in Cancun for two nights and then making my way down to Chatumal. Same on the way back, staying in Cancun for a few days before flying back to the UK.
Just 3 more sleeps to go !!!!
