Okay, here's the disclaimer: We did not choose this destination, nor did we pay for our stay. We were here for a family reunion, and the room was paid for by a family member whose company owns the timeshare or fractional or whatever designation they use. Park City is your basic western ski-resort town, lots of Native American trinkets for sale along a stretch of "historic" storefronts and saloons -- if you've been to Breckenridge or Aspen you've seen it all before (except it's Utah so there's a lot less ethnic diversity, naturally). There's basically nothing to do in Park City in the summer, which was fine since the Waldorf is a great place to do just that.
Our suite was flawless. The resort is new, so everything was in perfect condition, from the Viking range to the delicious beds to the Wusthof knives to the fluffy towels. We had a one-bedroom, two-bath suite that connected to the regular room of more family members, and we happily hung-out together in the living space of the suite, enjoying each other's company without tripping over anyone. We parents had the bedroom (really, the bed was delicious!), and our two kids camped out in the living room. The sleeper was very comfortable for one of our daughters, and the rollaway the other daughter used was equally good. There was plenty of room for the rollaway to be put up and stored in the room when not in use. We were a total of six people in the combined rooms and were all equally delighted with the space.
The pool area is divine. Sparkling pool, sumptuous (honestly) lounges, excellent service from the bar -- all combining to make for a great excuse to forgo the trip "downtown" for trinket shopping.
The workout area was a bit on the small side, but had everything we needed and was beautifully appointed with chilled water and towels. There even offer a limited number of group exercise classes, which we did not try.
The spa is spectacular. I had a massage (for which I did pay -- quite pricey, but very, very good). The shower rooms -- yes, each shower is its own room -- were amazing, and the steam room was very steamy. The anteroom/waiting area was stocked with elegant little snacks and chilled water, the staff was gracious and I was very impressed overall.
The lobby is very comfortable and well-appointed. We did not eat in the restaurant, but did enjoy cocktails and appetizers on a patio adjacent to the bar (back to the disclaimer: this was an owners' perk, for which we did not pay).
I have no clue what anything aside from the massage cost -- yes, it's okay to be jealous -- but I would gladly choose to pay top dollar to stay in this resort if were located somewhere I wanted to visit. I have absolutely nothing bad to say about our entire experience at the Waldorf. Top notch!
