If you already have a Disneyland ticket and reservation but want to purchase an additional ticket for another person (or another day), you must treat the second ticket as a completely separate transaction. Log into your MyDisney account on the Disneyland website or app and navigate to the "Theme Park Tickets" section. Select the ticket type and the number of days, and then—crucially—check the Reservation Availability Calendar before finalizing the purchase. Once the second ticket is bought, you must immediately make a separate park reservation for it. To ensure your entire group stays together, you can "link" the new ticket to your account by scanning its barcode or entering the ticket number. This allows you to manage park reservations and, later, Lightning Lane selections for the whole "party" at once. In 2026, keep in mind that having a reservation for one person does not "save" a spot for another; you must secure a confirmed reservation for every individual ticket in your group before the park reaches its daily capacity.
