Hey there Clarissa,
Thanks so much for visiting us here at planDisney! This is an excellent question, so I'm glad you stopped by.
Currently, to visit one of the parks of the Disneyland Resort, you need both valid
theme park tickets and a
theme park reservation for each day of your visit. Depending on when you purchased your tickets, you likely made your theme park reservations during the purchase process.
My recommendation for seeing those (and making or managing any other reservations for your upcoming trip) is the
My Plans hub on the Disneyland Resort website. On this page, the top section has buttons that lead you through the booking process for all the different kinds of reservations available for your stay. The bottom section shows you any current reservations - listed for each day.
If you have already made those theme park reservations, this is my recommendation on where to find them! If you need to change your dates, this is a great spot to do that as well. You'll see the option to modify your current theme park reservations next to each day in the My Plans hub as well. Just click the link next to the day(s) you want to change and it'll walk you through the process.
Thanks again for your question, Clarissa! Here's to a fantastic trip to the Happiest Place on Earth and a happy 2024!
Have a Magical Day,
Greg
