Disneyland is a theme park in Anaheim, California, which opened in 1955; it is the only one designed and built under the direct supervision of Walt Disney, who came up with the concept of Disneyland after visiting various amusement parks with his daughters in the 1930s and 1940s. He initially envisioned building a tourist attraction adjacent to his studios in Burbank to entertain fans who wished to visit; however, he soon felt that the proposed site was too small. 

Disney California Adventure Park, commonly referred to as  California Adventure  or by its acronym DCA, is a theme park located at the Disneyland Resort in Anaheim, California. It is owned and operated by The Walt Disney Company through its Parks, Experiences and Products division. The 72-acre (29 ha) park is themed after the history and culture of California, which celebrates the adventure of the state through the use of various Disney,  Pixar  and  Marvel Studios properties. The park opened on February 8, 2001 as Disney’s California Adventure Park and is the second of two theme parks built at the Disneyland Resort complex, after Disneyland Park.
