Everyone [member=2639]Dubb[/member] mentioned was there for work except Drake (not sure what he's doing these days) and AJ - she was prob there to support Aly though.
Actually Drake voices Spiderman on one of the Disney XD cartoons, so he could have been there for work reasons.
I didn't see as many celebs as I usually do (outside of press rooms, of course), but I did ride in an elevator with Alan Tudyk as he was on his way to the Syfy Live taping.
