response: Have you ever gone to the Preview Night the Wednesday evening before it starts? You get to walk around the exhibit hall.
original_response: I was interested to find out that on the Wednesday prior to the official opening, guests for all 4 days can attend a ''Preview Night'' and walk the exhibit hall before the convention begins. How cool!
history: Do you follow San-Diego Comic Con? I just know that it's held every year in San Diego. Oh cool, I usually follow it every year to see the movie trailers and stuff that come out of it. That's cool. It's apparently four days long and held in the summer. Yeah a lot of people put a lot of work into their costumes. It is pretty cool.\
knowledge: On the Wednesday evening prior to the official opening, professionals, exhibitors, and pre-registered guests for all four days can attend a pre-event ''Preview Night'' to give attendees the opportunity to walk the exhibit hall and see what will be available during the convention.
