Hey there Luis Victor,
Welcome to planDisney - I'm so glad you stopped by with your question! It looks like you have a trip coming up right around
Halloween. What a fun time to visit! Have you started counting down the days, yet?
Luckily, the names on your
theme park tickets are more to help you stay organized than anything else. When you visit with your group, a Cast Member at the entry gate will take a quick picture of each person in your group as they scan their ticket. It's this photo, attached with each individual ticket, that will be what is needed when entering the park.
If everyone has their own ticket linked in their
Disneyland mobile app then you should be good to go. Where I've seen some trouble with this is if you have one or two group leaders that have the tickets on their phones and then the group splits up. Ultimately, you'll just want to make sure that if someone leaves the park for some pool time or a nap, they have their associated ticket when trying to re-enter the park.
If it would be helpful to have names re-assigned to your tickets, you can also
call a Cast Member at the Tickets line who should be able to help with that. However, once again, the names are more to help you keep your tickets organized when visiting.
I hope you have such a fun visit to the Disneyland Resort, Luis Victor! Make sure to catch a showing of
Halloween Screams during your visit. It's one of my favorite nighttime spectaculars. Thanks again for your question!
Have a Magical Day,
Greg
