Flight to KC you mean, right? Wait until you see ticket prices for the game. Single game tickets aren't on sale yet. Upper sides are about $700 on StubHub, corners less (packed in very tight over there, students have most of the corners). Where are you staying for $150 that you can walk to AFH? The Oread is really the only walkable hotel and it is already sold out (and would be more than that). How are you getting from MCI to Lawrence?
Not trying to discourage any Husky fans from the trip, I hope many make it, just being realistic. The TownePlace Suites on New Hampshire downtown is nice and is $215 for two Queens. SpringHill Suites is a good location too, an old mill on the river that used to be an outlet mall. I would not trust air travel on the day of the game, but that's just me.
This game being a Tuesday is a bit of a bummer. Debating whether to make the effort, if I do it will probably be so I can introduce another Husky fan to AFH.
