Hi, Giuliana! Thanks for bringing your question to planDisney!
You'll be glad to know that you do not need to change the name on your theme park tickets before you visit the parks. Disneyland Resort theme park tickets aren't officially assigned to an individual until the ticket is scanned at the gate and a Cast Member takes their photo. From that point on, the same person needs to always use the same ticket, but the name digitally attached to it doesn't matter.
If you haven't already, be sure to download the
Disneyland app before your trip. It will be your best tool for navigating the parks efficiently. You can use the app to see current attraction wait times, mobile order food from quick service locations, and it will be how you use the new
Disney Genie and Disney Genie+ services that will be launching soon. Disney Genie+ is an add-on feature that will allow you to skip most of the wait at select attractions by using the Lightning Lane. It will be $20 per day, per ticket.
I hope this helps. Have a magical day!
