NEW YORK – Some 50 hotels across the country are giving away a free night to guests who can prove that they completed at least eight hours of community service between July 1 and Dec. 20. To qualify, you must provide a letter on the nonprofit organization's letterhead proving that you've completed the volunteer work at a 501c3 organization. Many steam and railway preservation organizations qualify.

The hotels, all managed by Sage Hospitality, include The Nines in Portland, Ore., The Blackstone in Chicago and the Sheraton Tucson Hotel and Suites in Arizona. The room must be reserved at least 48 hours before arrival. Guests must pay taxes for the room. Blackout dates apply and there are a limited number of rooms available at each hotel. The offer runs to December 20, 2009.
