This item is a set of (4) Disney Park-Hopper Passes.  Tickets expire 09/02/2019.

In Disney-speak, Park Hopping means that you visit more than one of the four Walt Disney World theme parks (Magic Kingdom, Animal Kingdom, Epcot, Disney’s Hollywood Studios) in one day. If you want to go to more than one of these parks in a single day, then you need to have the Park Hopper add-on for your Disney theme park ticket.
