Hilton is running a fantastic winter sale of 50% off on properties on stays from December 14, 2012 to January 7, 2013. This is great for anyone planning on traveling during the holidays and still haven’t booked rooms. (Or you might be able to rebook at these rates instead!)
In order to get in on the deal, you have to book via the Special 50% off Hilton page here.
Plenty of great rates available in the U.S.!
