EPCOT HOLIDAY TRADITION: Neil Patrick Harris, the Emmy Award-nominated star of the hit television series “How I Met Your Mother” and former star of the hit series “Doogie Howser, M.D.,” will be the guest narrator for the Candlelight Processional at Epcot Nov. 29-Dec. 1, 2007. Presented in the World Showcase America Gardens Theatre at 5, 6:45 & 8:15 p.m., the event is one of the most beloved holiday traditions at Walt Disney World, featuring a joyous retelling of the Christmas story by a celebrity narrator — accompanied by a 50-piece orchestra and a glorious mass choir.
