Hi there, Michelle. Welcome to planDisney. I'm glad you stopped by!
Your question didn't mention if you have a standard theme park ticket or a
Magic Key pass, so I am providing information for both... just in case!
If you have a standard theme park ticket and need to modify or cancel a park reservation, you have until 11:59 PM Pacific Time the night before the reservation to do so. If you don't cancel or modify before that time, you will need to wait until the reservation day ends before being able to reschedule your visit. If you have a Magic Key Pass and you fail to cancel by 11:59 PM Pacific Time the night before, your Magic Key will get a "no-show" if you don't make your theme park reservation. If you get three no-shows on your Magic Key in any 90-day window, you cannot make new park reservations or modify existing park reservations for 30 days.
Michelle, to modify your theme park reservations, find "Theme Park Reservations" on the
"My Disneyland" tab of the
Disneyland Resort website. Click on the blue "Make or Modify Park Reservation" button and it will take you to a list of your Upcoming Theme Park Reservations. Click on "Modify Reservation" or "Cancel Reservation" on the right of the reservation you want to change. Before modifying or canceling any reservation, I highly suggest checking the calendar for availability for your new desired date and theme park. If you are a Magic Key holder, you can book park reservation dates three months out. I like to book my must-visit dates as soon as they first open up to ensure we get a reservation.
If you have any more questions, please stop back by, Michelle. I'd love to help!
Have a magical day,
Melissa
