Hi Larissa! Welcome to planDisney! I'm so glad you found us to ask this question and I'm happy to help!
I'm sorry that mix-up happened with your tickets! Hakuna Matata, which means no worries! When you arrive, you can have your daughter scan the
theme park ticket that was mistakenly assigned to your sister, and your sister can scan the ticket that was assigned to your daughter. The names won't need to be corrected because a Cast Member will take a photo of each person with each ticket upon entry.
I hope this helps to ease your mind and that you're getting excited about your visit that's just days away! Whether you are visiting
Disneyland Park,
Disney California Adventure Park, or both, I hope you have so much fun at
The Happiest Place on Earth!
When you're ready to experience the magic of
Disney Parks again, I hope you will let us help you plan! You've got a friend in us at
planDisney!
See ya real soon!
Smiles,
Lisa
