Yeah, I'm out there for 4 months, so I checked out the rec center in Silverthorne this fall (it wasn't too far off the highway, ask around). Minimal gym, but ok, and BIG pool and indoor outdoor hot tubs. The deals were either 3 or 6 months, and the six was around $300 (sorry I'm so vague).
The competition is in Breckenridge, at similar prices, I'm told, but I haven't seen it.
Considering the amount of resorts, I'm thinking that some may take temporary customers, considering the market. I'll find out in January.
