Hello Saurabh and a very warm welcome to planDisney!
If your plans change, it’s easy to adjust your dates and take a magical vacation to the
Disneyland Resort when the time is right for you! So go ahead and select the most likely dates of your visit! But, if you need to, you are welcome to change your dates. To modify your
Theme Park Reservation, please log in to your Disneyland Account and select "My Disneyland." Then, click "Ticket and Reservation Details" and select "Cancel Reservation." After you receive the email confirmation of cancellation, you’ll be able to book a brand new theme park reservation for your desired date. Because Theme Park Reservations are limited and subject to availability, be sure to check the
Availability Calendar before you attempt to change your reservation. This will allow you to confirm that both your desired date and theme park are accepting reservations for your ticket type.
If your tickets expire before you are able to visit, don't worry! According to
eTicket Terms & Conditions, unless otherwise stated, the amount paid for any wholly unused, expired Disneyland Resort theme park ticket (with the exception of Special Event Tickets) may be applied towards the purchase of a new theme park admission ticket at the current price. The new ticket purchase price must be equal to or greater than the amount paid for the original ticket. So, if your tickets expire before your next trip, simply go to a Main Entrance ticket booth upon arrival and ask a Cast Member to apply your eligible ticket amount towards a new ticket purchase.
I hope this information helps! Thanks for dropping by with your question!
