We stayed at Keystone Resort (during the summer, on a trip to Colorado) using points. Keystone is part of the Conciege Collection. We had a 1 Bedroom condo that overlooked a courtyard area which had a number of shops. Our building was considered "ski-in" from the slopes and was a, maybe, 5 minute walk to the chairlift. It is also close to Breckenridge (about 30 minute drive). There was a laundry room and each room is assigned a locker for storage of gear.
We would go back in an instant, though we prefer warm weather locales for our winter travel.
