Or, if you don't have these VIP tour tickets, you can pick up free tickets at the White House Visitor Center. During the busy season, people start lining up outside the Visitor Center as early as 4am to snag one of the approximately 4,500 tickets distributed daily. A National Park ranger stamps the hand and takes down the name of each person in line and the number of tickets, up to four, the person wants. To gain admittance on the tour, someone in your party must have the magic stamp and the right name. The ticket counter closes when the supply for that day is gone.
Tickets are valid only for the date and time issued.
