Well, the printout inside the envelope states:
Thursday 12pm-8pm for just about every event for the day
Friday 10am-7pm for same as above
Saturday 10am-7pm for same as above
Sunday 10am-7pm for same as above
Monday 10am-4pm for same as above
Some events (Vader helmet art exhibit, family room, Lucasfilm archieve) close at 6pm.
I know my volunteer schedule states I need to be to the autogrpah hall at 9:30 Friday, which makes sense because we have to be there 1/2 hour before the doors open and Thursday, my shift ends at 8:30 (1/2 hour after close).
I was really hoping that the con would last longer than 8pm....I guess I'll head over to the store then and stand in line
PS: Nothing is open until midnight except the store, which runs 24 hours until 2pm Monday.
