Had 6 of us in the 2 bed with fold out sofa bed. Sofa bed was bumpy and very noisy. I cod hear every toss and turn my kids made.
You're really stuck if you are wanting a hotel room close to the western entrance to Yellowstone National Park. The town, as well as the hotel, seems to be stuck in the 1950s, so there aren't a lot of great options, especially when you are looking for value. At Days Inn, you get a coupon for breakfast at the on-site restaurant, but that doesn't cover beverage, tax and tip, which came to six bucks for me. The room was old enough to have window unit A/C units, and was really dated. The location was perfect, only minutes from the park entrance, but if the hotel had been in a town without a major attraction, I wouldn't stay there for forty bucks. Even with a discount, I paid more than quadruple that.
