We were #72 in the reserved line, there were 2 types of lines, reserved and unreserved. reserved had access first. I would gander there were probably over 400 in the reserved line and probably at least as much in the unreserved, though I'm not 100% sure on that. We spent the night participating in random activities and we got to win prizes, make a wand and a broom bookmark, see real live owls, and get our picture taken as Harry Potter (woohoo to free glow in the dark HP glasses!).
Otakon was also fun, but honestly more time this weekend was spent/dedicated to Harry Potter. Read the book cover to cover in around 12-13hours all day Saturday. (Amy read hers in probably 6-7hours, I'm a slow reader, what can I say?!)
