We are told that the original block of rooms at the Sheraton Hotel is sold out. They have added a handful of double rooms to the block, but those won't last the week. If you have yet to make your housing arrangements, we'd recommend you get right on that. Fortunately, there are some other really close options.
Holiday Inn Express is less than 100 yards away from the site of the Con. In fact, it shares a parking lot with the Sheraton. If you made it to GameHole con last year then you'll remember that parking can get tight so walking to the Con is an excellent option.

If neither of those options work out there are several hotels in downtown Madison which is about two miles a way.
