Yes, adding the "Park Hopper" option to your Walt Disney World or Disneyland ticket requires an additional fee. In 2026, this is a flat-rate add-on that applies to the entire duration of your multi-day ticket; you cannot choose to "hop" on just one day of a four-day pass. The cost typically ranges from $65 to $85 per ticket, depending on the season and the number of days on your base pass. This feature allows you to visit multiple theme parks on the same day, which is essential for guests who want to maximize their time—for example, starting the morning in the Magic Kingdom and ending with dinner and fireworks at EPCOT. Since 2024, Disney has removed the "2:00 PM" restriction, meaning you can move between parks at any time of day, provided you have made a park reservation for your first park (if required) and have entered that first park. For many, the extra cost is justified by the flexibility it provides, especially during shorter trips where you might want to hit the "headliner" attractions in different parks without dedicating a full day to each one.
