Here is a list of schools that did walk-ins in Chicago last year at the Palmer House. This list is not necessarily comprehensive (there may have been more) and there is absolutely no guarantee that the list will be the same this year (some schools offered walk-ins last year due to the snow forcing some students to cancel auditions):
UAB
Viterbo
Utah
Western Michigan
Ball State
Cornish
Drake
LIPA
Royal Welsh Academy
Ohio Northern
Oklahoma (Acting)
SCAD
CAP21/Molloy
NYCDA
Long Island U.
Northern Colorado
In addition to those shown above, some programs offered walk-ins at other hotels. We didn’t venture outside the cozy confines of the Palmer House (due to the arctic blizzard conditions) except to get Do-Rite donuts, so I didn’t get a list of walk-ins at the Hyatt, etc.
