I just want to pass a warning of what happened to us at one of the hotels near Arrowhead back in '02 at the Eddie Robinson game.
We had reservations for 3 or 4 rooms I made the previous year - pretty much when the announcement of the game came out. About 2 or 3 weeks before the game, I get a letter stating that they can't honor my reservation due to some remodelling. Turns out there was also convention in town and they were honoring those contracts ahead of the earlier reservations. They wanted to relocate us out in Blue Mound or some such place - about 20-30 miles away, whereever it was. After many phone calls and heated conversations - they "found" room for us.
It was one of the hotels across from the stadium. I don't want to name names, let's just say it rhymes with Holiday Gin.
I suggest to all to keep tabs on their reservations and confirm periodically.
As for recommendations - do a search for Bed and Breakfasts in KC. I did a few weeks and found quite a few. Most are reasonably priced. Even a couple down in the Plaza/Westport area.
