Excursions Get a decent Mexico guide book from the bookstore.
They contain little maps of the areas, places to visit, and most importantly, things not to do. Don't get a book the just lists hotels and restaurants, get one that is for backpackers or for traveling by rental car. You won't have to wait in line and won't draw much attention from local peddlers. We have not yet tried renting a car while in Mexico, but it certainly looks easy. Driving at night is probably still too confusing for me - someday I will understand the confusing patterns of tailgating and headlight flashing that seems to be necessary for night driving.
