I haven't been to ACen since 2008--how much has changed? in ACen Discussions/Questions Posted February 12 · Report reply A lot has changed since 2008. Attendance has doubled since then, and while I can’t remember the exact number of exhibitors that were there in 2008, Hall A is entirely filled with Industry booths and Exhibitors. In 2008 the hall was still being shared by many things, some panels, the Artist Alley, etc. If you’re looking for a specific Exhibitor, there is a listing of who is coming on our website (http://www.acen.org/exhibitors-industry/participant-listing/). Registration has been really streamlined since 2008. Last year, I don’t remember seeing the at-con registration being longer than an hour during peak times. This can be avoided too by having your badge mailed to you. ACen also expanded into other areas of the convention center, a lot. We have a separate hall for the Artist Alley, taken many of the ballrooms for panel programming, and last year moved video gaming into another hall.
