The search for Rancho Don Andres Careyes shows one link to a pdf that says golf and Pollo.

So I assume that is where the Polo events are held. Can't say for sure as I have never been to one of those events nor have I heard of anyone playing golf up that way.

"Not everything revolves around the foreign visitors"

Going by the same search as above one could make the argument that the primary market of Careyes is foreign visitors. Ones that are Well to do, as reflected in the price of the event.
