We were on vacation with our family in Vail, and brought along our tennis racquets. We showed up at the Vail Racquet Club unannounced, and were able to get a court right away. It was $15 for an hour, and $20 for an hour and a half. This is somewhat less than the club where I play at home. The courts are Har-Tru clay, and I had never played on it before, so that was interesting. I didn't find any special difficulty playing on the surface. You are encouraged to brush the courts with brushes provided on each court after you finish playing, which took a few minutes. The staff was helpful and friendly. They had complimentary sunscreen if you forgot yours (which we had!). All in all, it was a great time spent in Vail on vacation.
