...as FD1971 suggests, you may get an upgrade without using your points.
I would call the hotel. I find them to be rather accomodating, so perhaps a direct discussion will gain you the room you desire - with or without points.

The hotels in the ' burbs just aren't that great.

I beleive the best to be in Oak Brook, but that is about a 1/2 from Schaumburg, so may not fit your needs.
