From the Newseum website:
July 1 through Sept. 5, 2011, youth visitors 18 and under get free admission to the Newseum with one paid adult admission. Offer is limited to up to 10 kids. This promotion is not valid in combination with other discounts. Summer Fun Deal tickets, like all Newseum tickets, are valid for two consecutive days.
Ranked by TripAdvisor as the No. 1 attraction in the nation’s capital, the Newseum has something for everyone.
The Newseum offers a wonderful experience for everyone in the family. From the Pulitzer Prize Photographs gallery, Elvis, the 4-D theater to the Newseum’s interactive exhibits. There is a lot to explore and a lot to learn at every age level.
