Stayed here with friends over a weekend. One of my friends first time to Banff. The hotel was great. The decor and atmosphere fit well with the mountain surroundings.
The room was great. We had a 2 bedroom suite with enough comfortable sleeping for our group. The only issue we found with the room is that the snow got into the room and the floor was constantly wet since you enter the room from an outdoor courtyard.
The highlight is the grotto. We were sitting in the cave like hot tub with snow coming through the hole in the roof - very cool.
All in all, it was a great stay, and I would not hesitate to stay there again the next time I'm out that way.
