Ye Olde Carlton Arms: http://www.carltonarms.com: (click on reservations): Basically like staying in a hotel in a Call of Cthulhu adventure -- in a good way. Colorful, eccentric, extremely cheap, great for people who want to share room. One block from amazing food options, 17 blocks from venue.
The Gershwin: http://www.gershwinhotel.com: Very hip, very cool, a bit more expensive than the other options (but not that expensive). For those who want to travel in style. Good food options. 19 blocks from venue.
I'm trying to arrange a room-sharing deal, but if you can work it out yourselves, go ahead and book a room.
We'll open up registration for the actual event very soon.
