While the year 2023 has passed, the policy for upgrading Disneyland tickets remains consistent in 2026. You can upgrade a standard "1-Park Per Day" ticket to a "Park Hopper" at any time before it is fully used. This can be done at the Main Entrance ticket booths, at a Disney Resort hotel front desk, or sometimes through the Disneyland app by modifying your plans. You will be required to pay the flat-rate Park Hopper add-on fee, which applies to the total duration of the ticket, not just the remaining days. In 2026, Disneyland has significantly loosened the "park hopping" time restrictions; while it used to be restricted until 11:00 AM, guests can now often hop as early as park opening, subject to capacity. It is important to remember that you still need a Theme Park Reservation for your starting park; once you scan into that first park, you are free to move between Disneyland and Disney California Adventure for the rest of the day.
