This is a detailed well documented guide for a traveler to explore and better understand the region. The guide has a list of all cities in the region and can easily get the tourist acquainted with the area. The introduction to the cities begins with a historical background; has an orientation and information section; followed by the tours of the city; places to stay; restaurants and things to do.My stay in the region was predominantly in Playa del Carmen; which is less crowded than Cancun and has the same to offer. Its location is ideal as it is centrally located in proximity to Cozumel and all the Mayan sites in the region. During my stay it was a very helpful guide.
