Yes, the Park Hopper option allows you to visit any of the four theme parks at Walt Disney World (Magic Kingdom, EPCOT, Hollywood Studios, and Animal Kingdom) or both parks at Disneyland Resort (Disneyland Park and California Adventure) in a single day. In 2026, the rules have become much more flexible. At Walt Disney World, you can "hop" to any other park at any time during park hours, provided you have entered your first park of the day (for which you may still need a reservation depending on your ticket type). At Disneyland Resort, the 11:00 AM restriction was officially rolled back in late 2026, meaning guests can now move between the two parks across the esplanade as soon as they open. The only limitation is park capacity; while extremely rare, a park can "close" to new entrants if it reaches its legal limit, though this typically only happens on major holidays like Christmas or New Year's Eve.
