I've been to one and those autograph sessions are mad! If I were you I'd invest in All Access VIP if you plan to get a heap of autos done - saves heaps of time in line. The autographs cost heaps though, generally much more than what you can buy them for on the secondary market or an autographed card. Some of the guys are pretty cool to speak with though and if you want a particular inscription it can be well worthwhile. Definitely bring a fold up chair or something....this year it's in Chicago and I went to the same place for my convention too! If you need any advice just send through a PM
