The Waldorf-Astoria is a fantastic property for those looking for a full-service (nearly) ski-in/out hotel in Park City. The facilites are, obviously, first rate. The staff is even better.
We had a minor snafu at check-in, and I was placed into a standard single king, despite needing two separate sleeping places. As a Hilton Gold, I was dismayed to hear we had not been upgraded, although the hotel was fully booked, so I understood. After a couple of hours, the front desk was able to find an alternate room which was excellent. The ski staff are also great. It's a huge bonus to be able to store equipment with the hotel; they have a room for putting on boots, jackets, etc, and they take your skis up to their gondola. It's all run very efficiently.
The big theme of the hotel is service and convenience. From the easy valet and check-in, to the great shuttle to downtown to the ski services, everything is taken care of. In the suites, there is even a washer/dryer combo! This was an awesome and unexpected perk.
I'd highly recommend this property to those visiting the area.
