I went to Disneyland during Super Bowl XLII and literally, it was deserted. There was nobody there. They let us ride Space Mountain four times in a row before making us get off the ride for others. Probably the best time ever. Anyways, I went back to the hotel happy as hell, turned on the TV, saw the Patriots lost and that ruined my vacation. So there you have it. Seeing as how you are a Chiefs fan your vacation probably won't be affected by the outcome of the big game.
