Literally hundreds wait in three different lines at this very moment at TwiCon. One line is for registration and "problem-solving," the other (split into two, actually) for entrance into the vendor circle, and the third (and by far the longest) is for the 100 Monkeys autograph signing session that will end shortly. Jackson Rathbone is not in attendance.
The biggest complaint from attendants is the fact that, at this event, the right hand doesn't know what the left is doing. There are so many different employees and assistants that they simply do not know who to refer you to when something is needed. As a result, nothing moves quickly and the fact that the event is a new one is a secret to none.
