For Priceline name your own price, the areas closest to most of the tourist sites are (in preference order IMHO): #5: Convention Ctr - Capitol Hill area #13: White House - Downtown #8: Dupont Circle - Woodley Park #9: Georgetown - Foggy Bottom Stay away from #7: DC Suburbs - Northeast Area If you're doing name your own price, hopefully you'll get lucky and get a hotel near a Metro. The Renaissance on 9th St, the Grand Hyatt, JW Marriott and Willard are all walking distance to Metro stops. 3 star in the zones mentioned above should be fine. For lower costs, you can go to #6: Crystal City which has a Metro stop and the hotels have free shuttle buses to Reagan Airport where you can also catch the Metro. You can get all day Metro passes that are good after the morning rush hour (930a).Details about the subway at www.wmata.com May 31 is Memorial Day and the city clears out of business travelers, so you should be able to find some good prices if you can beat the tourists making their reservations. Since Congress will be out of session, you might be able to find some good prices in the Capitol Hill zone.
