July is a nice time of year to go. I know the area well, as well as the Kaatskill Mtn Club. Tell me what you want to know, and I'll try and help you out. Let me know what you are looking for in the area, etc. Are you doing with a family? Couple? What kind of activities do you like?
As far as the KMC, the hotel is pretty nice overall. There is a pool, as well as two hot tubs. Overall, I'd rate the property as 3.5 star in my book. The place is well kept, but I find the beds and sofas could be better, though they are not horrible. The overall decor is pretty nice, and the staff is generally friendly and helpful. There are a lot of outdoor activities in the area that time of year like hiking, horseback riding, ATV riding, golf, etc. There are a bunch of restaurants that are good in both nearby Windham and Tannersville. Overall I think it's a very nice place to stay if you like the outdoors/mountains.
