Hi Megann, welcome to planDisney!
Not to worry, I've actually made the same accident! And it's a super easy fix. Keep your current
theme park reservation, and on the day of your visit, head on over to the
Disneyland Resort Main Entrance Ticket Booths. Let the Cast Member there know that you have a reservation for that day, but that you accidentally purchased a child's ticket, and that you need to upgrade to an adult ticket. They can absolutely help you out!
And you chose a great time to visit the Disneyland Resort!
Holidays at the Disneyland Resort will kick off on November 11, 2022, through January 8, 2023, so your timing is perfect! There is so much going on at the parks during this time. You'll get to experience multicultural and diverse music, cuisine, and traditions, and of course, you can't forget about the special Holiday overlays!
World of Color – Season of Light,
Mater's Jingle Jamboree, and
Luigi's Joy to the Whirl are all returning to
Disney California Adventure Park. At
Disneyland Park, you can expect to see
"it's a small world" Holiday,
Haunted Mansion Holiday, and of course one of my favorites, the
"Believe…In Holiday Magic" Fireworks Spectacular! Fun times ahead!
See ya real soon!
