The two-day park hopper ticket allows ticket holders to access all associated Disney parks for each day of the pass. They are available at Disneyland and Disney World theme parks.
At Disneyland in California, the park hopper ticket is for access to both Disneyland and Disneyland California Adventure. In Florida at Disney World, the park hopper ticket provides guests access to the Magic Kingdom Park, Disney's Animal Kingdom, Disney's Hollywood Studios and Epcot Center.
The park hopper ticket is added onto a traditional ticket upon purchase, whether online or at the theme park. Without it, each theme park charges a separate entry fee.
