We're heading to Mexico, Belize, and Guatemala over Xmas for a 5 week family holiday - first time to these countries.

You can't do it all, but we're trying to see a wide range of what Mexico has to offer... Tulum, Campeche, Merida, San Miguel de Allende, Palenque, MC.... with another 9 nights in Belize/Guatemala.

Interesting reading the comment above regarding Palenque... we'll be driving in from Villahermosa.

Interesting to compare JDiver's map with the travel warning issued by the Australian Government ... we've used this as a guide along with a good dose of commonsense!
