Howdy, Christian! Welcome to planDisney. Thanks for popping in with your question, I am happy to help!
I’m sorry to hEAR you had to cancel your reservations to visit
Disneyland Resort on January 30, but happy to hEAR you're considering experiencing the magic a day earlier! Your ticket can be upgraded to use on a different day. Typically, you would need to visit the Disneyland Resort Main Entrance Ticket Booth to upgrade tickets, however, I suggest you contact Guest Services in advance of your visit, as you may not want to take a chance that theme park reservations are no longer available when you arrive on January 29. My preferred way to reach Guest Services is through the "Chat with Us" feature in the
Disneyland mobile app – this way I can send in my question and will receive a notification once a helpful Cast Member has been able to get back to me. You can also reach a Cast Member
via phone if you prefer that method. They can help you upgrade your ticket by paying the difference, so you can secure a theme park reservation in advance for your new desired date.
Christian, I am not sure if you have yet experienced the phenomenal cosmic power of
Disney Genie+, but during my recent visit it was a whole new world being able to access
Lightning Lanes and reduce our wait times in queues. You can add Disney Genie+ to your day via the app as soon as you enter the theme park!
Sending you some pixie dust as you make your ticket and reservation changes. Have a magical visit!
