I got to go to this hotel as a prize and we had a "standard view" room. Um, there's nothing standard about this view! It was amazing! I found the staff very nice, and the hotel was beautiful and majestic in the rockies!! I didn't eat there because it was crazy expensive, except for the conference I was attending, I would say the food for the conference was average...your typical conference food, nothing spectacular but not bad.
If you can afford it - stay here! If not, then Banff is magical as it is and you can stay somewhere cheaper I'm sure!
