Hailed as the most groundbreaking theme park of its time, Epcot marks its 30th anniversary on Oct. 1, 2012, and D23: The Official Disney Fan Club is preparing a unique celebration of one of Disney’s crowning achievements. On Sunday, Sept. 30, 2012, D23’s Epcot 30th Anniversary Celebration will whisk D23 Members back to a time touted as when “the 21st century begins”—those early Epcot years when guests first marveled at “Astuter Computers,” “Smellitzers,” and the novelty of “riding on sunshine,” and were awed by a massive geodesic sphere called Spaceship Earth. This journey to yesteryear, the future, and around the world takes place one day only: on Sunday, Sept. 30, 2012, from 9 a.m. to 5:30 p.m. inside Epcot (Park admission is required and not included in the event ticket price). Each D23 Member may bring up to three guests.
