As it turns out, the Levy Center room that would be the right size is already booked up for the time we would need it. But they transferred me to the Evanston Ecology Center, which has a fabulous room, that is probably even nicer for our purposes:

(And by the way, the Best Western never even got back to me about a room and/or catering, nor did the other places where I left messages. I swear, why are people so flaky? At my job, even if I can't help someone, I always call back and let them know.)
