If you're looking for an affordable hotel stay sometime soon (and who isn't these days?), consider Orbitz's seven-day sale, which started today.
Use promo code 20HOTEL, and you'll save 20 percent off your entire booking, no matter how many nights. I found a $44 per room per night rate at a San Francisco Travelodge (close to the airport, but still a good deal) with the discount.
Book by Jan. 18 (this Sunday) for travel through Apr. 30, 2009. The 20 percent discount is good only on hotel stays—not vacation packages.
Also new at Orbitz is Deal-O-Rama. On the 1st and 15th of every month, Orbitz will post new regional deals, offering a 10 percent discount on hotel stays or $75 off a three-night vacation package. The current deals are for California.
