Light Up The Season, the annual community fundraising event benefiting Children’s National Hospital, will be held, 1 to 4 p.m., Sunday, Dec. 15, at the Four Seasons Hotel on Pennsylvania Avenue.

But you can view the designer Christmas trees, Hanukkah menorah and other holiday décor in the Four Seasons lobby right now — and purchase those very items later to benefit Children’s National.

Their designed Christmas trees, mantelpieces, menorah and dollhouse are available for purchase, with proceeds directly supporting programs that improve the health and well-being of children across the Washington, D.C., region.
