The last time I rode through Glacier National Park and the Going to the Sun Road, I was on my motorcycle, so I can't give you much help in places to stay etc. but I'll be interested to hear what responses you get. We are hoping to get to Glacier this summer on our western trip. I have no desire to take the camper on that road (not sure they would even let me if I was dumb enough to try) but I would like to camp near there and take the tour of the road.
