Hello there, Gabriela! Welcome to planDisney. We are so glad you stopped by with your ticket question.
As Mickey Mouse says, oh boy! I'm sorry to hear that in your excitement of booking your tickets, you accidentally purchased child tickets instead of adult tickets. As frustrating as that can be, I promise you aren't the first person to accidentally do this. The easiest way to get this fixed and upgraded to adult tickets would be to call
Ticket Services or chat through the
Disneyland app and see what they think is best. However, if you are already in Anaheim, the other option would be to get to the Main Entrance Ticket Booth located in the Esplanade between the two parks as soon as possible and get them upgraded there. They will need to not only upgrade them but rebook your ticket reservations as well, so the sooner you do this the better.
Once you get that all cleared up you will hopefully be able to rest easy and get excited for a magical visit. I definitely recommend that you take the time to see
"Magic Happens" parade. The details and vibrant colors of the whole show are just so visually stunning and the music... you will be bouncing your shoulders and dancing along!
Gabriela, thanks again for stopping by! Have a wonderful time at The Happiest Place on Earth!
Carrie
