I have been traveling to Mexico since studying Spanish in Cuernavaca in the mid-1980's. I just purchased this volume to have a more current guide for a trip I am making to Mexico and Guatemala this summer. I was particularly looking at Oaxaca, Cuernavaca, Palenque, and San Cristobal de las Casas. Things I really like about this guide:
1. Pretty good city maps which show bus stations, dining, lodging, banks and places of interest. Unfortunately, at my age I now find it easier to read maps with some type of magnifier, but they are helpful.
2. Not bad recommendations of things to see and do and helpful information about how to get to nearby places of interest.
3. Small tables of bus destinations from major cities giving approximate cost, travel time and some idea of the number of daily departures.
4. Occasional data on such things a local bus rutas for getting around a city -- particularly liked the ruta for getting to the Casino de la Selva bus station in Cuernavaca for picking up a direct bus to the Mexico city airport. I may use a taxi, but it is nice to know how to do it by the city bus.
The descriptions of places I have been look pretty well written and that gives me some confidence that the locations I have not yet visited are equally well-described.
My favorite places in Mexico include Guanajuato, Mexico City, Cuernavaca, Morelia, Patzcuaro, Palenque, San Cristobal de las Casas, Puebla, Guadalajara and environs and Oaxaca. The information for those areas looks solid.
I have many Mexico guidebooks and this one is perhaps the best I have used to date.
