InterContinental Hotels, which is the parent company of Holiday Inn and Crowne Plaza Hotels (among several other brands, like Candlewood Suites and Hotel Indigo), have started running 24-hour Flash Sales, where select hotels are 50-75% off when redeeming points for a reward night.

For example, hotels that are normally 35,000 points per night will be only 8750 points per night like the Crowne Plaza in Athens Greece.  Check out the full list of participating hotels on the IHG website.

The 24-hour sale starts at 10:00 am EST tomorrow Monday, October 21, 2013.  Rooms are limited, so if you see a hotel that interests you, jump on it as early as possible!
