AmP in Chicago briefly?

I might have a chance to visit Chicago from March 2nd to 3rd with a few friends. I've never been to the windy city - so I'm excited.

As always when I visit a new town, I welcome tips of places to visit and things to see - especially Catholic sights and sounds. Holy Name Cathedral is sure to be on that list, recent fire damage notwithstanding.

And of course, it someone has or knows of a spare couch - I've never been one to willfully support the hotel industry.
