Joanietoo . . . let me know . . .
I don't get out much (too much work, limited budget), but if you can provide some basics - WHEN you will be here, WHERE you will be staying (Loop, Mag Mile,) WHY you will be here, WHAT you are interested in doing, etc. I can probably offer some insight on what to do, how to get around, places to eat.
Chicago is a BEAUTIFUL city, which I am sure you will fall in love with.
PS Chicago got cold last night. Be prepared.
