The one nice thing about the Hilton is that celebs do stay there. A fun thing to do is call the front desk & have a celebrity paged, then watch for all the people who gather in the lobby to see if he/she shows up.
I know you already booked your hotel, but for future reference and anyone else reading...the Vikings used to stay in the Minneapolis Hilton the night before games. I'm not sure if they do anymore, but when I went to Minny in 2000 we stayed at the Hilton. I got to see a bunch of players, was on the elevator with a few and met Cris Carter outside the hotel lobby. Not sure if they still stay there or not...but that's food for thought.
