I'd offer you space in my room, but I'm using staff crash space, so >> (hey, it's free)
Btw, a great idea for helping out with not having a place to stay is just flat out volunteering at the con. Generally, random volunteers get at most no more than 12 hours of assigned work throughout the entire weekend...they are also REALLY good usually at working around other stuff you want/need to do...as long as you show up to WORK your shifts...
But anyway, for giving them 12 hours (possibly) of work, you get a free badge, free place to sleep (no credit card needed!), free food, a special staff tshirt...and it's also a GREAT way to make friends. And frankly, it's tons of fun! I may bitch and moan about everything I end up doing at the con, but I have met some of the NEATEST people by volunteering, and now, at my fourth A-kon, I am a staff head.
And most of the jobs are pretty darn simple. For first timers, I'd recommend Registration, KAOS room, Komik Market, etc. I'd recommend Jpop room, but I am overstaffed >>
Anyway, just a thought.
I think they still have volunteer forms open, too.
