Really? The only thing that you need to know about spanish is reading the signs, other than that not really. You got tourist guides, and if your going down under a
vacation organization like MCI, they plan out guides that tell you about the area. No need to really learn the language, unless you really want to, its just as if your going to japan, and you dont need to know japanese. Think of mexico as other
vacation places..except..much much hotter.
