Mom and Dad reserved three large condos in Park City for a destination family reunion. This worked out well for a three day reunion because many of our family live on the Wasatch Front, so some people could go to work during the day and meet us up there at night. It became an annual spot for a few years, until we decided we wanted variety. We stayed at the Silver King and shared large condos.
There is plenty to do in Park City like the Alpine Slide; and Adventure Park for kids; shopping, ski lift rides; etc. And now they even have a zip line. We loved the condos. (I think now it is listed as a hotel). They had big screen TVs out in a hallway alcove where we gathered to watch a movie together, and some of the larger condos had indoor hot tubs.
My husband and I rented a vacation house up there for a few days just four our family. We all loved being all together in the same house. The kids watched a movie downstairs in the family room, and we played games upstairs.
