If anyone is looking to book a hotel for the tour (or any other reason) I just searched for hotwire deals and found they are offering $30 off any 4 start booking!
You can only use it once (per email address). To get the deal just go to http://www.retailmenot.com and search "hotwire". It should pop up right at the top. The deal is only being offered for 10 days, ending 11/30.
We just got a 4 star that's about 2 miles from The Vic in Chicago for $61.32 tax included.
