If you are looking to combine practical luxury with the great outdoors and nature of southern Alberta, the Crowsnest Mountain Resort is a superb choice. I stayed there first in 2011, and returned in 2012. There are only five or so cabins, so you have to act fast to secure a reservation especially for peak times.
The cabins are clean, well decorated and outfitted with all you need. Comfortable bed with soft duvet, kitchen with dining wear and living room with futon that makes into a bed. CMR may not be the Ritz Carlton, but it isn't "roughting it" either. Practical yet comfortable.
Never had a problem with mice (in October) or any other unwelcome creatures. The staff and management was incredibly friendly and accommodating. I believe they are Swiss, and the Swiss are known for their hospitality and hotel skills. The CMR could as well be in the Swiss Alps. I kinda liked that they didn't have housekeeping every day, but only on request. Housekeeping at most hotels usually come at the worst time. Here, I could order it when I wanted and needed it. A great convenience actually.
What is special about CMR is - without a doubt - the location. Just enough outside Coleman (3 km) to make it seem remote, yet close enough to the towns and places you need to be and see. Since its a bit remote, you have an INCREDIBLE night sky - with the Milky Way cloud totally visable. Plus, you have a superb view of Crowsnest Mountain (the pic I included was taken on-property).
The worst thing about the resort was there are only 5 cabins. I wish there was more non-RV accommodations. Perhaps villas would be good, as long as they don't destroy what makes CMR special - the nature.
In the Pass, you gotta check out The Grand, RumRunner and Blackbird in Coleman, and the Bellevue Inn (Karoke on Th-Sun nights).
