Three Bear is just down the street from the West entrance to Yellowstone and is convenient to many stores and restaurants (just don't take advantage of the convenience of Three Bear Restaurant).
The room we had was a suite and was large, clean and comfortable.
Sound does seem to travel so a second floor room is advisable. However, you have to take the stairs to get to the second floor so if you have issues carrying bags up stairs, that's not for you.
Rooms at the front can get a lot of road noise with snowmobiles running past and guests idling trucks for extended periods.
The hotel also runs what appears to be very successful snowmobile rental and tour businesses so the lobby can be busy first thing in the morning.
Overall, a pretty good hotel with a great location.More
