While I liked some things about this book there are a few of things that drove me crazy and made it hard to use. One is the method of using a numbering system for hotel prices. It took me a long time to find the key to this system which is located near the beginning of the book. Why can't they just put the actual prices and separate the hotels into budget, mid-range, and high-end categories the way Lonely Planet does?
Another frustrating thing was bus information. Near the end of my trip I found that they have information at the end of each section listing bus routes for that region, but in most cases not much information about schedules. When is the last bus of the day? The first? Can I get from San Cristobal to Oaxaca? Reading this book you would not know if it is possible, yet there are three direct buses a night.
The third issue, and possibly the worst failing of this book, is the quality of the maps. They are much smaller and less detailed than Lonely Planet's. In one case a recommended hotel was misplaced on the map causing me to walk around for an hour looking for it until I finally resorted to going to an internet cafe to look up the hotel's location on line. Also, the hotels and restaurants are indicated by letters and numbers on the map, but these are not cross-referenced on the descriptions of the establishments so what I would do is look up the name and letter then write the letter next to the hotel description for easy reference.
The index is also very poor. For example, I had seen some information about whale-watching and couldn't find it again. The index made no reference to the page I had seen, but when I finally did find it, it was a featured activity for the region!
The book does make interesting reading as another reviewer said, but I wonder if he or she has ever actually tried to use it as a guide.
