By Air: book your flights to Acapulco international airport (airport code ACA). Below are the maps of Acapulco and Mexico. Acapulco is the farthest south of all the Mayan Resorts, making warm weather almost a guarantee. Sun is also a sure thing except for September and early October.
The Grand Mayan and Mayan Palace Acapulco are a short 10 minute cab ride from the airport. Make sure you specify to the cab driver Grand Mayan or Mayan Palace, so you end up at the right part of the resort. Here is a Acapulco Mayan Resort map. Once you are settled into the resort, it is a approximately 20 minutes by cab or bus to the tourist areas of downtown Acapulco. If you are driving in from Mexico city, the express way exits just a short drive from the resort. Small sleepy beach villages make for a nice drive to the south.
