You're posting in the Hilton forum. Were you looking for Hilton specific info?
There is the airport Hilton and the one downtown. You'll be more comfortable with a rental car if you stay at either one. There used to be a ski bus from the downtown hotels but it now requires a connection to Trax. I don't have specifics on the properties. Don't know if the Homewood Suites in Midvale is on the skibus route.
If you are happy with either of the Cottonwood Canyons and don't want to drive then check the UTA website
www.rideuta.com and look for lodgings on the ski bus route.
Park City fans will weigh in I'm sure.
Ask if you have specific ?s
