Thanks for the replies. We actually decided on the Ritz for the full hotel resort experience. My parents spend a lot of time in Jackson Hole and decided that if they were going to spend the weekend at a similar resort, they preferred not to be in one that is just as crowded and busy.
I know Beaver Creek is a busy summer destination as well, but we're hoping to avoid some of the crowds by staying at the hotel and taking advantage of the amenities it has to offer.
