Barack Obama will be the host with the most on Inauguration Night. After his expected swearing-in ceremony earlier in the day on January 20, he’ll host seven inaugural balls and attend three more for a grand total of 10.

Moving among the various official parties won’t necessarily require a motorcade, though: six of them are being held in the vast Walter E. Washington Convention Center. These include Obama’s home states ball, hosted by the president-elect for invited guests from Hawaii and Illinois; Vice President-elect Joe Biden’s home states ball for guests from Delaware and Pennsylvania; the Mid-Atlantic regional ball, the Midwest regional ball, the Western regional ball and the neighborhood ball, which is for Washington DC residents and other guests.

The bargain event of the night may be the youth ball, hosted by Obama for guests aged 18-35 at the Washington Hilton, with tickets available at $75. Most of the other balls cost $150.

Rounding out the list are the Eastern ball, to be held at Union Station; the Southern ball, at the National Guard Armory, and the Commander-in-Chief’s ball for enlisted active duty and reserve military personnel, at the National Building Museum.

That last location is particularly appropriate for military guests. Before it was a museum, it was known as the Pension Building, built to serve the needs of Union veterans after the Civil War.
