I have been to park city many times before.
I stayed in the hotel where the restaurant and Minyan which is called the "Silverado Lodge". The hotel is mediocre at best. No ski in-ski out. The plus is that you are right on top of the restaurant, and right near the Shul.
The Hyatt, is ski-in-ski-out, and I hope it will be a little better.
the restaurant is great, and the sandwiches mid mountain are divine.
