Just saw a special on the broadmoor on the travel channel and want to use my points to stay there. It is at the base of pikes peak and a beautiful resort for adults and kids. You might want to check and see if it is going to be on again soon.
We stayed at the River Run Resort at Keystone for a week in Feb. It was wonderful. A nice place and lots to do. We had a one bedroom for 224 point at peak ski season. Good luck.
If you are looking for an II exchange I would stay at the Grand Timber Lodge in Breckenridge. We took a tour of this resort two summers ago and were totally blown away. Very beautiful resort! If you were staying in the winter it might be tough to get in because it is ski in / ski out. But during the summer you might not have a problem. We thought that the rooms were nicer than most DVC rooms.
