I'm planning a trip to Chicago. Want to attend an event at Symphony Center. It looks like the least expensive way for us to fly there is to go through O'Hare airport. Can anyone recommend good places to stay near the Center, preferably within walking distance. (But, should we even be walking in Chicago after dark? Everything I read tells me violent crime is a popular hobby there, and I cannot bring my 18 little friends with me for backup.) Is there public transportation that would connect the Symphony Center with O'Hare? I ask here as I will most likely be both traveling and attending the event kilted. I've never visited Chicago before, other than to pass through Midway airport on the way to and from elsewhere.
