Hi there, Olivia,
Yes, in most cases, you may cancel a
theme park reservation and
reschedule to another date for which the associated
theme park ticket is still
valid. In your case, however, you would first need to upgrade your
one-day tickets from Tier 1 tickets to at least Tier 2 tickets. The most straightforward way to upgrade park tickets is to visit a main entrance ticket booth at the Disneyland Resort. Note that when a ticket is upgraded, any existing park reservation tied to that ticket would be automatically canceled and a new reservation made before it can be used to enter a theme park. For that reason, I recommend either visiting a ticket booth ahead of time as early as possible or calling a Cast Member with the
Tickets phone line.
I hope you can get to the Disneyland Resort soon, Olivia. That way, you can experience one of my favorite Disneyland Resort entertainment offerings that recently returned to Disneyland Park: the "
Magic Happens" Parade. It has some of the coolest floats. And the character interactions are so fun!
I hope you have a magical time, Olivia!
