Disney has announced significant expansions at its theme parks, revealed during the D23 convention. The Magic Kingdom will see the largest expansion yet, featuring a 'Cars'-themed area in Frontierland, replacing Rivers of America and Tom Sawyer Island, and a new villains-themed land with two major attractions. Additionally, a new nighttime parade called 'Disney Starlight' is set to debut in 2025. Disney's Hollywood Studios will get a 'Monstropolis' land with a first-of-its-kind suspended coaster, while Animal Kingdom will feature an 'Encanto'-themed ride and a Tropical Americas section by 2027. These new developments demonstrate Disney's commitment to delivering immersive storytelling and thrilling experiences.
