If you wanna take advice from a German who has never gone to the NFL Experience.
It seems to be quiet fun but you need to buy tickets in advance, they allow people to go in only in groups at certain times, so you have to buy the tickets in advance and state the time you want to enter.
If you want to get an autograph (for free I think, no idea who signs, but should be about 50 players) you have to hurry up. People told me that the people entering the hall usually run 1st to the McFarlane booth to buy the SB exclusive figure and to the auto boots to stand in line. Somebody said that for Feeley he had to wait 1 hour to sign. So you can imagine how long you would have to wait for somebody like Neon Deon. On the other hand this wAS WHEN EVERYBODY THOUGHT THAT Feeley had a shot of being the next Fins QB and not just the backup of a backup.
