Destination D.C. is the official tourism and convention corporation for Washington, D.C., 901 7th St. NW, 4th Floor, Washington, DC 20001-3719 (tel. 800/422-8644 or 202/789-7000; www.destinationdc.org). Before you leave home, order (or download from the website) a free copy of the bureau's Washington, D.C. Visitors Guide, which covers hotels, restaurants, sights, shops, and more and is updated twice yearly. At the tel. 202/789-7000 number, you can speak directly to a staff "visitor services specialist" and get answers to your specific questions about the city.
Besides using Destination D.C.'s website to obtain a copy of the visitors guide, you can read about the latest travel information, including upcoming exhibits at the museums and anticipated closings of tourist attractions. The website is also a source for maps, which you can download and print from the site or order for delivery by mail.
Once in D.C., you can stop by Destination D.C.'s offices on 7th Street NW (Metro: Gallery Place-Chinatown, H St. exit), to pick up the visitors guide and maps, and to talk to visitors services specialists. Office hours are Monday to Friday, 8:30am to 5pm.
If you're arriving by plane or train, you can think of your airport or the train station as visitor information centers; all three Washington-area airports and Union Station offer all sorts of visitor services.
Also look for business improvement district (BID) offices and their patrolling "ambassadors," who dispense information, directions, and other assistance in their individual neighborhoods.

Take a look at the D.C. government's website, www.dc.gov, and that of the nonprofit organization Cultural Tourism D.C., www.culturaltourismdc.org, for more information about the city. The Cultural Tourism D.C. site, in particular, provides helpful and interesting background knowledge of D.C.'s historic and cultural landmarks, especially in neighborhoods, or in parts of neighborhoods, not usually visited by tourists.
