As of early 2026, there is no official limit to the number of times you can "park hop" between the four Walt Disney World theme parks (Magic Kingdom, EPCOT, Disney’s Hollywood Studios, and Disney’s Animal Kingdom) in a single day, provided you have a ticket with the "Park Hopper" option or an Annual Pass. Following the 2024 policy updates that restored "all-day" park hopping, guests no longer have to wait until 2:00 PM; you can move to a second, third, or even fourth park immediately after visiting your first reserved park. The only functional limitation is park capacity. While it is rare, if a park reaches its maximum legal occupancy, Disney will pause entry and send a notification through the "My Disney Experience" app. Additionally, you must have physically entered your first "reserved" park of the day before you can hop to another. This flexibility allows for the famous "Four Park Challenge," where ambitious guests attempt to experience an attraction and a snack in all four parks between sunrise and park close.
