The queues were just too long and the stands too close together. There was plenty of space in the hall, so I don't know why they crammed everyone in 1/4 of it.
It was pretty much fighing for the chance to go through each box of comics, people had 'lists', they weren't budging. I did however get quite a few X-Men back issues I needed, some Wolverine, X-Force #1 and a book of Matt Dixon (really cool dude) with a A3 print both signed.
No, I didn't meet Stan Lee, no chance. There was tiers, and panel rooms, and more queues. There were however quite a few badly dressed people in costumes. A guy dressed as Gambit made me laugh loads. Lots of Rogues, saw a Deadpool, a Bruce Lee, lots of Spiderman, Shrek (?)
Not to bad experience, at the time it didn't seem like fun, but I got some good comics and filled many gaps in my collection, so good result!
