OK. Poor planning on my part. Forgot to make a reservation for our first night (this Sat)! We land in Spokane around noon and after shopping for groceries I don't think we will get into West glacier until after 6pm. It looks like most of the campgrounds are filling up before noon. We have to stay on the west side since we leave for Sperry Chalet on Monday.
I'm thinking that I am out of luck and will need to stay at a hotel/motel or sleep in my car :(
