For Friday the autograph and dealer room hours are: 5pm-10pm. Saturday is 10am-6pm for autographs and 10am-7pm for dealers. The pre show is gamble really because all the preshow does is get you into the dealer room an hour early. Sometimes (but they arent obligated) some guests come down a lil early so if they are at their table then you can get their autograph at the same time.
