A Hopper ticket to Disneyland or Walt Disney World offers access to all of the company's parks in a certain location in one day. Normally, tickets allow entrance to only one park per customer per day, but Hopper tickets allow customers to "hop" between parks at will.
In the company's Southern California location, a Hopper ticket offers daily access to both Disneyland and Disney California Adventure, while in the Florida location the options include Magic Kingdom, Epcot, Disney's Animal Kingdom and Disney Hollywood Studios.
Disneyland was the company's first park, and the only one built under the direct supervision of Walt Disney, though the idea for the "Florida project" was his, and he was involved in the initial planning. Disneyland was completed in 1955. The company started its Florida resort location in 1971 with the opening of Walt Disney World. Epcot was added in 1982, and is dedicated to the celebration of human achievement throughout the world. Epcot proved the success of the multi-park model, leading the company to open California Adventure in 2001. That park was less successful, though the company has worked to retool its offerings to make it more appealing. Disney Hollywood Studios, originally Disney-MGM Studios, opened in 1989, while Disney's Animal Kingdom opened in 1998.
