Hey Adina!
Welcome to planDisney! Thanks for stopping by with your question!
There is no need to change the name on the unused theme park ticket before your visit. Upon arrival at the Main Entrance turnstiles, a Cast Member will take a picture of the person using the ticket. Then, the ticket is associated with the person in the picture, not the name on the ticket. Leave everything as it is and head straight to the turnstiles when you arrive!
If you have not done so already, make sure to download the
Disneyland Mobile App ahead of your visit. You can use it to check attraction wait times and access the daily entertainment schedule. But, my favorite use for the Disneyland Mobile App is
Mobile Food & Beverage Ordering! Choose your preferred
Quick Service location and pickup time frame. When your pickup window arrives, select the “Prepare My Order” button and wait for the text alert that your order is ready for pickup. Then, head to the pickup counter to retrieve your order. It's so easy and convenient!
Thanks again for stopping by! Enjoy your visit to “The Happiest Place on Earth!”
