US 93 doesn't go through West Glacier. If you are going to pick it up at Kalispell, MT, then go north to Radium Hot Springs, BC, the 2-lane road is mostly in a river valley and is fairly easy driving. From Radium Hot Springs to Lake Louise, AB, you cross a couple of passes, if I remember right. Lots of small towns between Kalispell and Radium Hot Springs, but very few north of there when you get into first Kootenay, then Banff, National Parks. Radium Hot Springs is a major tourist area and the roads there are packed with cars and RVs in the summer.
We stayed a Johnston Canyon (near the intersection of 93 and 1) on a trip a few years ago and at Lake Louise last summer on our way home from Alaska. Lake Louise has electrical hookups, Johnston Canyon doesn't.
