Shane's right. I made a thread to organize something around this a month ago, so yeah, I'm in.
There will be couch space, as well. I have a couch, a love seat and a full sized air mattress, plus some floor space. We fit four or five people here last time and we could probably fit a couple more if necessary. My place is small, but it's an option. I'm not going to put forth any real fair rules on my space: I will be handing it out based upon how well I get along with you (Though preference will, of course, be given to those who need it). This is, of course, likely to be irrelevant, as I can't think of anyone who might be coming who I'd turn away.
For those who can afford a hotel, I'd recommend
Harding House in Cambridge. It's a bed and breakfast that is, literally, right across the street from me (And has wireless internet. I should know, I've leeched off of it before).
Here's also some hostels in the area:
