Depends ... If you are directed to any stairwell, and then told to go down, as in towards the basement, do this: 1). Excuse yourself, say you need to use the bathroom ... pretend to be having cramps, blame it on dinner the night before, and embarrassingly say "this might take a while" 2). Head for the bathroom, until you are out of sight 3). Break for the nearest side door 4). Take a taxi to the airport; pay with cash 5). Change your ticket at the counter, and get on the first flight out of O'Hare 6). Go into "radio silence" mode If you're lucky, you can board your flight and take off before the goon squad at the Park finds out you're making a run for it. Picture the final airport scene from the movie Argo ...
