Not that kids need any more reason to want to visit the Happiest Place on Earth, but Disney California Adventure Park gets even better this month. Three big additions—Cars Land, Buena Vista Street and the Carthay Circle Theatre open June 15 at the expanded park. Cars Land is a 12-acre exhibit inspired by the Disney-Pixar movie Cars, featuring three new attractions— Radiator Springs Racers, Luigi’s Flying Tires and Mater’s Junkyard Jamboree—as well as dining and shopping. Buena Vista Street will serve as the new entry point to Disney California Adventure Park. The streetscape replicates 1920s Los Angeles; visitors can ride in vintage trolley cars, take in the 1920s-era theatre and dine at the new Carthay Circle Restaurant, which is expected to become the top dining destination in the park.
