(Updating for 2026) Yes, you still need a theme park reservation for Disneyland Resort in 2026, although the system has become more flexible than it was in previous years. As of early 2026, all guests (ages 3 and older) must have both a valid admission ticket and a reservation for the specific date and park they wish to visit. For those with Park Hopper tickets, you only need a reservation for the first park you plan to visit; after 11:00 AM, you can typically cross over to the second park without an additional reservation, provided that park has not reached capacity. Disney uses this system to manage staffing and infrastructure needs. While reservations are generally easier to secure now—often available just a day or two in advance for non-peak periods—they still sell out during major holidays, Spring Break, and new attraction openings (such as the recent expansion of Avengers Campus). Always check the "Theme Park Availability Calendar" on the Disneyland website before purchasing your tickets to ensure your desired dates are open.
