On the route through Mexico!

Here is a MAP of the route we want to take across Mexico:

     This route starts in Mexicali, Baja California and travels south into Baja California del Sur. We will take a ferry ride from La Paz to Mazatlán, Sinaloa that will take 17-18 hours overnight. From Mazatlán, we will travel down 15 into Jalisco, and then take a rambling path through the central valley through the states of Guanajuato, Queretaro, and Puebla, down into Oaxaca where we will be in the clear of any dangerous zones of the country.
     From Oaxaca into Chiapas, through Villahermosa, Campeche, and into the Yucatán, we will finally get to Chicen Itza where we will see beautiful remnants of the Mayan civilization. From Chichen Itza we will hit up Cancun to relax in some nice touristy beaches. From Cancun we will head south through Quintana Roo to the southern border city of Chetumal where we can cross into Belize!

     This leg of the trip, according to Google Maps, will take 79 hours, almost 3.5 days. But add in nights when it's dark and we can't drive, tourist time, and eating, and pit stops, that is already up to 6 days! And that's not included unforeseen circumstances....
