We have a trade through RCI into Crestwood Resort, Whitefish, MT for August this year. In researching airfare and car rentals, it is to our advantage to fly Southwest, as I have two free tickets. The nearest airport seems to be Spokane, with a 4 1/2 hour drive from there. Has anyone done this drive? Is there anything scenic to see or do on the way? We will be using Whitefish as our base to explore Glacier National Park.
