We stayed here during week of President's day with our 6 and 9 year old daughters and had a great time. The rooms were comfortable and well-maintained, and the decor pleasantly reminded me of 1970s/1980s "modern", which is probably about when it was built/designed. The pool and hot tubs were great as was the daily shuttle to and from the lifts. If you don't have young children, you could easily walk to the lifts, though perhaps not the first day if you are not used to the altitude.
The managers were very helpful, with our requested humidifiers waiting for us in our rooms. There were pleasant even when I yelled at them when I was suffering from mountain sickness the first night and couldn't figure out how to switch the bathtub faucet to the shower (there is a ring around the spout that you need to pull down).
If you are looking for luxury, this is not the place for you, but if you are here for the skiing and need a clean, reasonably priced well-maintained condo with two hot tubs, a pool, and other very friendly guests, the Wren is great.
