I'm going to be visiting Chicago from late Thursday evening (arriving around ten) and leaving mid afternoon Saturday.  Staying at a five star hotel downtown.  Would love to have company while there but my schedule is kind of in flux, so some situations may mean calling on short notice, and I don't know how workable that is.  Generally, more available in the evenings but may still be a bit on the short notice side.  Saturday early afternoon meeting also possible before heading out.  Any suggestions/volunteers?
