Epcot Center has added three new attractions since it opened in October. They include the Electronic Forum, the ride-through portion of Journey Into Imagination, and an exhibit of ancient Chinese sculpture, including bricks from the Great Wall of China.

Electronic Forum guests can choose from national, regional, and international news and sports, weather, and business news via satellite on touch-sensitive television screens. They can register their opinions on interesting topics in Future Choice Theater, where computers instantly tabulate and display results of the electronic poll.

Summer hours at Disney World will be extended at least until midnight in both parks. A special summertime Magic Kingdom feature, the sparkling Main Street Electrical Parade with twinkling lights outlining its many floats, dancers, and character performers, begins nightly performances in mid-June.

At least three days is advised for seeing both the Magic Kingdom, with its 45 adventures, and the new Epcot Center Future World and World Showcase, with 15 major themed areas. The three-day passport, giving unlimited admission to both parks, is the most popular form of ticket, which costs $35 for adults, $33 for juniors (ages 12-17), and $28 for children (aged 3 to 11). Children under 3 are free.
