As a Hyatt Platinum member, I have stayed at my share of Hyatt Hotels and this was by far the worst. The hotel was severely understaffed: after being out of the room skiing for 6 hours a day, we routinely returned to a room that was not cleaned. There was not a single day we were able to enjoy a clean shower after a full day of skiing. There were never enough valets- we called for a pick up at the base of the mountain several days, and nobody ever showed up. (Luckily, the Waldorf Hotel was nice enough to drive us back.) And, inevitably, the bell hop or two on-duty were helping with luggage so they could not retrieve our car. The only bright spot was the ski valets, who were helpful-especially Matt Bost. He was on top of things and recommended the best skiing for our family. Unfortunately, the trail back to the hotel was under construction so you could ski out-but not really get back to the hotel at the end of the day. Beyond that, the decor was nothing special and the room was so hot and dry, we were up all night. Would recommend Deer Valley if you are headed to Park City. We were surprisingly disappointed.
