The conference venue is the Illinois Conference Center which is connected to the I-HOTEL located on the southwest part of the campus of the University of Illinois Urbana-Champaign. Therefore, the I-Hotel likely the most convenient place to stay for the duration of the conference but far from the only convenient option.
There is a 85-room block at the I-Hotel which can accommodate some, but not all, of the conference participants. Fortunately, there are numerous nearby hotels that are within a mile or two of the conference venue. These hotels are shown below (distance from conference venue shown in parentheses):
