This is a small issue, but I don't know if it was addressed earlier: I was volunteering for registration lines and a LOT of people registering at-con couldn't seem to figure out the difference between the registration and the payment line. Maybe it could be a little clearer next year so that those waiting for their friends/family to finish don't accidentally wait inside the registration room (and annoy the staff inside)?
Also, in general, instead of mailing out badges, can we simply expand the number registration booths (which might require moving to another location) so that even if the line is long, it would move super fast? I was lucky and only waited 2 hours Friday afternoon for mine, but I know for others they weren't so lucky :\
On a positive note, Artist Alley and Dealers Hall was absolutely amazing! I think I circled it a few times each day because I couldn't pick what I wanted to buy (without blowing my budget)! xD And the Swap Meet and pocket schedules were totally awesome

Love that Swap Meet was expanded to the Fairmont ^^
