General Admission for BotCon?

Has anyone done the General Admission for BotCon?
It's not my first choice but moving to a new house has left me looking at this as an option for still being able to attend at all.
As I understand from BotCon.com and the FAQ, General Admission is sold only at the boxoffice (not online in advance) and is per day and includes only the dealer room + whatever panels you can squeeze in to.
Assuming a person got to the box office at the buttcrack of dawn how likely is it even to get in on general admission? Does it sell out extreamly quick? Are there people camping over night?
Thanks for any advice guys, right now I'm just weighing my options and budget for going. Maybe some other fans here are looking at the same thing too?
