I forgot about the AAC huts as well. The Stanley Mitchell hut comes to mind. Open year round and quite nice accomodations. The Fryatt hut is also nice and is located in Jasper if you are coming from northern Alberta it's a easier drive.

Also worth going to is the Skoki Lodge. Located the the Skoki valley right near Lake Louise. It is a popular backounty ski spot and is open year round. Hike in is easy with many easily accessible peaks/lakes. Skoki Mt, Fossil Mt, Ptarmigan Mt, and Brachiopod Mt to name a few.
