Very odd place to put this question... Anyway to answer, the players are encouraged to stay at the Esmerelda and the Hyatt, but many of them are beginning to choose other places that are less well known and less popular (La Quinta Resort might be one of them). If you go to the official tournament website, you'll see a list of hotels suggested for ticket buyers. Those same hotels are suggested for the players (and press, and officials, and sponsors).
Pros should stop wasting money on coaches and doctors and just read the experts on this forum.
