I'm looking to take a roadtrip well south of the border this fall. Other than some daytrips to border towns, I've never spent any time in Mexico or points south, so I'd appreciate any tips from someone more experienced in this area.
My plan at this point is for a 7-10 day beach and jungle trip in October. We will be flying into Cancun and renting a car. The rough outline I've come up with so far has us driving down to the Costa Maya region (the southern most part of Mexico's east coast) and spending a day or two on the beach. Then we'll cross the border and head for the Cayo District of Western Belize, spending a few days in the jungle checking out Mayan ruins, caves, and possibly dipping into Guatamala. After that we'll head back east to the Belizean coast, probably in Hopkins, for a little more beach time, before heading back north to Cancun.
I've already found a couple car rental agencies that will allow international travel, but if anyone has a favorite rental company in Cancun, I'd like to hear it. I'd also like to hear about any budget/moderate priced lodging options in those areas or if anyone has any general driving tips (like avoiding the topes) for this part of the world, they would be appriciated as well.
