Salutations Marquita!
Welcome to planDisney! Thanks so much for dropping by with a question for us!
I’m so sorry to hear about your family emergency. But, I am happy to report that you are certainly able to cancel your upcoming
Theme Park Reservation and rebook for another day in the future. Let me walk you through the steps to make this change. First, log in to your Disneyland Account and select "My Disneyland" then click "Ticket and Reservation Details" and select "Cancel Reservation." Once you receive your confirmation of cancellation, you will be able to book a brand new theme park reservation for your desired date. The new reservation can be made immediately if you have a new date in mind, or at a later time if you're still unsure about your new plans.
Disneyland Resort Theme Park Reservations are limited and subject to availability. So, please check the
Availability Calendar to make sure your new desired date and theme park are accepting reservations for your ticket type.
I hope this helps! If you have any additional questions, be sure to send them our way!
