Other than what you might get here, you may want to contact the concierge at the hotel BEFORE you get there ...
The Palmer House is a beautiful, old hotel ... Like NY and other great cities, Chicago has a lot to offer /visitors/tourists ... Just standing at the shore of Lake Michigan is an experience in itself ...Hope the weather is good - you will have a great time ...
This could start you on your way:
