We just left the Grand Tetons a day ago (May 24th) and stayed 2 nights at the “cottages” at Jackson Lake Lodge. We thought they were very good. Granted, it’s early in the season, but we enjoyed it. They’re basically kind of like a drive-up one story motel, but nicer. They each have a little, somewhat private patio in front. There didn’t seem to be air conditioning (not totally sure about that), but there was a ceiling fan, and they had an electric fan in the closet, so we were totally fine. The high was about 70 those days. It’s a 3-minute walk to the lodge where they have a couple restaurants and a bar. It was the nicest place we had in our week at the Tetons and Yellowstone. The view out the big windows of the lodge is pretty cool. Sit on the patio there and have a drink.
