The official schedule with titles and abstracts (except for Joshua's) appears here.
At the same meeting there will also be many other special sessions that may be of interest to people in our session, such as Extremal and Probabilistic Combinatorics (organized by Jozsef Balogh and Dhruv Mubayi), Algorithmic Probability and Combinatorics, and Geometric Combinatorics (organized by Carly Klivans and Kathryn Nyman).
The meeting is being held in Chicago, IL, at the DePaul University

It is easy to get from either O'Hare or Midway Airport to the conference location on public transportation (CTA trip planner & main page), as well as most anywhere else you would like to visit while in Chicago. You shouldn't need a car. (If you do decide to drive, one place to park near the conference is Grant Park South or North for $25/day. Also note that traffic may be a bit of a mess Sunday morning due to the Chicago Marathon.)
The AMS has some hotel rooms reserved for the conference, however, you may be able to find something you like better. You should try to book early, since many hotel rooms are already reserved for the Chicago Marathon on Sunday. Use the above maps to to check that you are reasonably close and/or connected by public transportation.
One option is simply to use your favorite (on-line) agency to book a hotel.
Here are a few possibilities via DePaul University and IIT. (Unfortunately, all of these except Fairfield were sold out when I checked, but there will be cancellations so you may wish to try anyway.) DePaul has deals with The Palmer House Hilton and The Hilton Chicago, which are very close to the conference center; Fairfield Inn and Suites by Marriott, Chicago Downtown amd Best Western - River North are easily accessible by public transportation or by a not unpleasant walk [Click here for more information.] IIT has a deal with Club Quarters (two nearby locations, $129/night, you must mention "Illinois Institute of Technology").
You can get a hotel further away if you don't mind commuting, as long as there is a CTA train stop (The "El") nearby. (For example, on the Blue Line, between downtown and the airport.) We should be able to find some dorm rooms at IIT's main campus: Email Hemanshu (kaul AT math DOT iit.edu) if you are interested in this.
