Here is a list of all the courses I could find in the area. I think this is complete. They are grouped by location. The hotel zone may be a little quicker and easier to get to than Playa.

We play a lot of golf but not in Mexico so far. I have not priced golf. Generally the posted price is going to be $100 and up for the 18 hole courses, but there are probably deals if you look hard.

There are PGA tour events coming to the area in 2007 and 2008.

There are several new courses being built that will be fantastic, including a TPC course.

Cancun Hotel Zone:

Pok-Ta-Pok

Robert Trent Jones Jr. at the north end of the Cancun hotel zone.  Oldest course in the area, built in 1976. Much of the course is along the beach.
