There are a couple of threads on this property re quality of stay, e.g.

Better dining choices etc overall in Banff. Depends what you are going to be doing. Costs will be more in Banff but if you want to have wine at a fine restaurant (there are some good places in Canmore but Banff has the choice) and walk back to the hotel, this isn't the property to do it from.
