Hey, howdy, hey, Shirley!
Oh! I’m so glad to hear that you have recovered from the accident earlier in the year. Now, of course, it seems like a marvelous thing to celebrate at The Happiest Place on Earth!
To book new 
theme park reservations to the Disneyland Resort, you may visit the "
My Theme Park Reservations" page online. Log in to the same account that was used to purchase your 
theme park tickets then follow the prompts after you click on the “Book Theme Park Reservation” button. As long as the tickets are still valid, you may proceed to book new reservations linked to the same tickets from among any the the days and parks that the 
theme park reservation availability calendar indicates may still be booked. If you come across any issues along the way, you may reach out to a Cast Member via online chat or by calling the 
Tickets phone line.
I hope you’re ready for a 
rootin’, tootin’ time as you visit the Disneyland Resort, Shirley. If you have any more questions as you get ready to enter a “world of yesterday, tomorrow and fantasy,” feel free to visit us here at planDisney again.
