Yeap, Dr. Who was on Sunday last year and it was right after the Fringe Farewell panel and Supernatural panel @ Hall H respectively.
Just to give you an idea of how insane the queues are:
I decided to begin queuing (in full cosplay) at 2am and assumed that I'd be pretty ahead in line. BOY WAS I SO WRONG. Apparently, people had already started to queue at 9pm the night before, and by the time I headed down to the Convention Centre the line had already curled allll the way to the walkway facing the sea by the Hilton. Just so you know, most of them were Dr. Who fans, judging by their outfits.
By 5am there were people in the park-like area even further down. But once they start making people stand up and compress the lines, it got much better and we ended up in the first 1/3 of the room.
