This might be too late, and you don't earn points, but you can pretty reliably get the O'Hare Hilton for $35-$40 plus bonus on Priceline. I got two rooms for January 17 for $40 each.

Edited to add I just realized you are from Sweden and I don't know whether that affects your ability to use Priceline. Sorry.
