Given "NW Iowa" is your listed location, work your way backward towards home. I used to make the trek from up that way, and over the years have stayed in Boone, Carroll, Story City, Webster City, Fort Dodge, Humboldt, and Algona. Jefferson, Pocahontas and Storm Lake are probably viable options, too, depending how far northwest you have to go.
You get an hour or so on the road after the game (which isn't too bad), and then can be a little slower to roll out on Sunday morning since you're already that much closer to home.
