Howdy, Eavie! Welcome to planDisney!
I am so excited that you have a trip planned to the Disneyland Resort! I'm also glad that you are already using the
Disneyland app as that will be your best tool for navigating the parks when you visit.
There's no need to worry about the names assigned to your tickets in the app. Theme park tickets aren't officially assigned to an individual until they enter the park gates and have their photo taken. The name in the app won't change, but each person will continue to use the same ticket that they used to enter the park the first time. They will also receive a physical ticket that they can use for the remainder of their trip.
Each family member can also link their ticket (and the tickets of others) to their own Disneyland apps. This might be useful if several members are going to try to obtain a boarding group for
Star Wars: Rise of the Resistance or
WEB SLINGERS: A Spider-Man Adventure. And if anyone loses their physical ticket, they can use the digital ticket in the app to enter the parks.
I hope you have a fabulous time at the Happiest Place on Earth!
