Is Celebration, Fla., anything to celebrate? The Walt Disney Co.’s remake of the traditional American small town has its skeptics, but Mickey’s become quite the architecture patron, attracting many respected designers to the project. One of them is Robert A.M. Stern, who worked on the town’s master plan. He’ll discuss his firm’s contribution in a lecture, “Can Disney Deliver the American Dream?: New Urbanism in Celebration, Florida,” at 6:30 p.m. at the National Building Museum, 401 F St. NW. $7. For reservations call (202) 272-2448. (MJ)
