Beginning May 17, Disneyland Resort will roll out a new feature that will let Guests modify the date and/or park of their theme park reservations on Disneyland.com without having to cancel the reservation first, subject to park reservation availability and applicable block out dates. Guests using the app will be redirected to the website.
Guests will be able to make modifications to their theme park reservations up to the day of their reservation before they enter the theme park(s) and Magic Key holders will continue to have a one-day modification window.
