Hi Mary!
Welcome to planDisney!
The Disneyland Resort holds a special place in my heart as it was the first place where I fell in love with Disney magic. I’m always so excited when Guests are making their way to the Happiest Place on Earth to experience all the wonder and special moments awaiting them!
Mary, to switch park dates, you will have to cancel your initial reservation. You will need to log into your My Disneyland Account on the website, then click on 'My Plans'. Here you will see your park reservations, and you can click on 'View Details' for the date you'd like to remove, and press 'Cancel Reservation.' Once you've canceled your original date, you can then make a new
Disney Park Pass reservation. Simply follow the prompts under 'Make Park Reservations' in order to secure your new date. Once you've changed dates, the change will be noted on your My Disneyland Account and on the mobile app. Make sure you check the
Disney Park Pass theme park calendar before canceling to ensure that the dates and parks that you are planning to book are available.
I hope that this helps you make the most out of your visit to Disneyland Resort!
Malanie
