The National Archives Foundation today announced it has opened registration for its July sleepover in the Archives’ rotunda after this week’s sleepover sold out. The July 25, 2015, “History, Heroes and Treasures” sleepover invites 100 children (aged 8-12 years old) and parents to spend the night in the home of the Declaration of Independence, the U.S. Constitution, and the Bill of Rights.

Tickets to the sleepover are $125 per person ($100 for Foundation members) and are available at archivesfoundation.org/sleepover.

“The demand for this once in a lifetime experience in DC and across the country has been exciting,” said Patrick M. Madden, executive director of the Foundation. “Participants – children and their parents – create historic memories together and have a blast while exploring some of the nation’s most treasured documents.”

During the sleepover, children engage with National Archives records in fun and educational ways before rolling out their sleeping bags to spend the night in the historic National Archives Rotunda. The sleepover will feature numerous hands-on activities in the National Archives Museum through which young explorers can discover. Guests will also be treated to movies in the Archives’ William G. McGowan Theater before turning in for the night. The next morning, they will enjoy breakfast – including pancakes flipped by the Archivist of the United States – and more activities before departing with special memories, new friends, and a great story to tell when they get back home.

The Foundation held three sold-out sleepovers in 2014. Read more at Sleepover at the National Archives: 3 reasons your family will love it and watch a short video here.
