The historic Mammoth Hot Springs Hotel is a great place to stay at during a winter visit to Yellowstone. The rooms are simple but adequate and and there is a restaurant on location so you don't have to drive for meals. Walking distance to the actual Mammoth Hot Springs and a short drive from the northwestern entrance to the park. The onsite rental facility for snowshoes and cross country skis help make this a great staging base for exploring all the park has to offer. The restaurant offers pretty good variety and takes hospitality seriously.
It is always nice to wake up with elk outside your room window as well...

Remember when you are going to Yellowstone you are escaping the modern world. I visited the hotel and stayed in the main buliding not the cabins in January 2012. The rooms are just a bit smaller than the average hotel room. It is a historical building and upgrades are minimal.There is no TV ,and the rooms have a minimum of electrical outlets Some outlets were 2 pronged so I suggest bringing a power strip and adapter for all the chargers. The rooms lead toward the Spartan side and they are clean, warm, and comfortable. The staff is fantastic. You are located in old Fort Yellowstone within a 5 minute walk to the terraces at Mammoth which are simply magical. You also have car access to the Lamar Valley for spotting wildlife during the winter.This hotel is the only one accessible by car via Gardner ,Montana in the winter months.The only other hotel open in the park is Old Faithful Snow Lodge which is located in the southern end of the park and can be accessed only by snow coach.

The appearance is like entering a time warp back to the turn of the 20th century. Having said that it was very comfortable and although lacking in modern facilities, it was absolutely adequate and comfortable for my stay. Only problem was the electrical sockets were the old fashioned two pin type and no wifi. Reception said wifi will be available shortly.

We spent two nights at the mammoth springs hotel in Yellowstone National Park in January. The hotel is old and the rooms are adquate for the price. The lighting in each room is minimal but the beds are comfortable with adequate covers.

The hotel sits in the middle of old Fort Yellowstone. You must walk across the street to get to the restaurant. This is fine in good weather but when there is a blizzard it is a cold walk.

We did the snowmobile ride to Old Faithful. I would only recommend this trip to people who love snowmobiling. It is over 100 miles roundtrip and if the weather is cold and snowy it makes for a long and very uncomfortable day.

I would recommend using the snow coaches or staying at the Snow lodge at Old Faithful.
