Tourism in Las Vegas is down this year, and the online publication Travel Weekly recently reported that the average daily room rate in Sin City has dropped by 5.5 percent. In a gamble to win back the crowds, travel providers are slashing prices and throwing in discounts and extras.

Southwest is offering $50 off Las Vegas air-and-hotel packages of three nights or longer booked by August 7 for travel through mid-December. JetBlue's current vacation packages include two nights at Circus Circus and airfare from Long Beach for $145 per person.

If you're willing to spend a bit more, now is a great time to splurge in Vegas, since even higher-end properties have deep discounts this fall. US Airways Vacations has package specials at some of The Strip's best hotels, including the Wynn and the Bellagio. Continental Airlines Vacations has a third night free offer at Trump International Hotel & Towers.
