My understanding is that this program is fairly new and getting off the ground. We were fortunate that we were able to make a reservation the week we were there, but then again, it was mid May and WDW isn't quite as crowded then--in the future however, we plan to book well in advance; the cancellation time is 24 hrs. in advance. You can call the pro-shop at 407-824-3783, they are open from 9-12 daily. The courts are all clay, and the cost is $75. per hour, a little on the pricey side it would seem, but I can't stress enough that we thought the coaching and lesson were so wonderful it seemed like a bargain. In fact, I may even head back this summer just to give my ds some more time there--his game improved a lot with just two sessions. Oh, the coach we had was named Mike; he's also really good at relating the idea of what he wants the kids to do/change in their game so they can understand and do it--he used some little rhymes and things to help my ds remember. Also, FWIW, my ds was at the Stearns-Smith Tennis Academy in Hilton Head over Easter break, a school with a top reputation, but truly, I liked our experience at WDW a lot better. HTH.
