Welcome to planDisney, Amber Rose!
This is a great question! You'll be pleased to know that changing your reservation date is quite simple if your new date is in the same or a lower tier. All you need to do is sign in to your My Disneyland account and visit the
My Reservations page. You'll find a blue link that says, "View My Park Reservations." Click "Cancel" and then make a new theme park reservation by following the instructions under "If You've Already Purchased a Ticket" on the My Reservations page. However, let me encourage you to check the
Theme Park Reservation Availability Calendar first to make sure that your desired date is available.
Amber Rose, unfortunately, if you decide to downgrade your ticket to a lower tier you will
not receive a refund of the cost difference. If you need to upgrade your ticket tier, then you'll need to call a
Cast Member at Ticket Services (714-781-4636). They'll be able to wave their magic wand and get your ticket upgraded.
I hope that's helpful, Amber Rose. Have a wonderful time at The Happiest Place on Earth. Make sure you check out all the
Holiday festivities on offer during the Christmas season.
TTFN, ta-ta for now!
Mike
