Hi Tram, welcome to planDisney!
I have GREAT news, you can cancel your current
theme park reservation for your
One Park Per Day Standard Theme Park Ticket and book a new reservation all from within your
Disneyland Resort account! BUT if you want to upgrade to a park hopper, you'll need to visit any of the fantastic Cast Members at the Disneyland Resort Main Entrance Ticket Booth, and they can help you out. Another option to try is calling the
Disneyland Resort Tickets line at 714-781-4636 and see if the Cast Members there can help.
To cancel your current theme park reservation, you'll need to log in to your Disneyland Resort account, select the "My Disneyland" link, and then click the "Ticket and Reservation Details" link. Select the reservation you wish to cancel and click "Cancel Reservation". Once canceled, you're free to go ahead and book your new reservation.
And before I let you go, one more bit of GOOD NEWS! The
Disneyland Resort is bringing back its nighttime spectaculars this spring! On April 22, 2022, the
Main Street Electrical Parade and
Disneyland Forever fireworks will be returning to
Disneyland Park, and
World of Color will be returning to
Disney California Adventure Park! I've been waiting SO LONG for these to return and am ecstatic. I hope you'll be able to visit soon to enjoy them!
See ya real soon!
