Both are great hotels but I would opt for Hotel Park City in the summertime. Both are in somewhat unusual locations with not too much around them. The setting for Hotel Park City is a bit better on the golf course. But if you're in that price range I would also consider St. Regis, Montage and Stein Eriksen Lodge at Deer Valley.
thank you for your response. That is most helpful. We are a group of couples and we wanted lodging with a common area for lounging and a full kitchen which limited our options at St. Regis, Montage and Stein Eriksen. I did contact each of them. Stein Ericksen suggested The Chateux at Silver Lake which also offered me a very good rte.
OK, makes sense. The Chateux is good but I think you'll be better at Hotel Park City. It's across street from Stein's and doesn't have the same view or setting. Actually, knowing now what you want, you might look on VRBO for summer home rentals in Deer Valley or even Old Town. Odds are you can find a home for same or less.
I had trouble finding a home with four adult (as opposed to bunk bed) rooms with en suite bathrooms on VRBO. The price differential was not very great in those I did find and I figured the hotel service would make up for that.
Thanks for your help. If we end up in Park City (we are also looking at Jackson) I will be in touch for some more recommendations. You have been most kind.
