Hey there Jazmin,
Welcome to planDisney! I'm so glad you stopped by with your question, and am thrilled to hear you're planning a visit with such a large group - how fun!
I'm happy to share that the names associated with your
theme park tickets are really just to help with your organization as you're planning your visit. When you first arrive and everyone scans their tickets to enter a park, the Cast Member at the entry gate will take a picture of each member of your party with their associated ticket. This is what will determine who can use each ticket!
There is no ID required, but it's just this associated photo that will be used throughout the duration of your trip, so Hakuna Matata, Jazmin - you're all set!
If it would be helpful to still get the names changed on each ticket during your planning, you can
reach out to a Cast Member at the Tickets line who should be able to help you with this. However, again, it's certainly not required!
Additionally, it might be helpful if you all plan on linking your tickets together in the
Disneyland Resort mobile app. This makes it quicker and easier to make reservations as a group among other things. You can do this in the app by selecting the menu button (the three horizontal lines), then tap "Tickets & Passes," and then "Link Tickets & Passes." You can either scan all the barcodes or type in the ticket ID from here.
It looks like your trip will be here in just a few short days - I hope you have a fantastic visit and enjoy the Southern California weather! Thanks again for your question, Jazmin.
Have a Magical Day,
Greg
