Nice guide to phrases, and the dual English-Spanish/Spanish-English dictionary is helpful too. However, I found it difficult to find it to use "on the fly"... we traveled in the Yucatan (Playa del Carmen and Cancun) and I needed to have a few key phrases readily available ("How much is this?", for example.) This book isn't designed for quick access, and only has a few pieces that are useful. In general, it's more of a dictionary of short phrases and terms (it only has two pages devoted to common phrases). I would have preferred a guide to common phrases like "Where are the bathrooms?" and "My hotel room smells bad." That said, though, it is a nice sized little book and would be useful for anyone traveling to Mexico. It's small enough to fit in your pocket.
