We (two adults 60+ and two adults 30+) stayed here to visit Grand Tetons & Yellowstone.
Clark's Knoll was a wonderful home base: extremely comfortable; clean; and perfectly located. We had an easy drive to the Tetons; could walk (or hop the free bus) to downtown Jackson; and also enjoyed the neighborhood.
It was the off season (mid-May) so Snow King was closed, but it would be an ideal location during the season, as the gondola is literally across the street.
FWIW for anyone planning a trip, it was definitely worth it to stay in Yellowstone one night but also have Clark's Knoll booked. We were able to return, do laundry and have a hot meal "at home" when the weather turned rainy and cold in the park.
Also, plan to bring your own salt, pepper, oil, etc., as none of that is stocked.
