Hey there Cindy,
Welcome to planDisney and thanks so much for your question! I live in Arizona, so I definitely understand the heat - I'm glad to hear you're considering visiting at a time when the weather is better for you and your granddaughter! My family and I visited for one day last July and we had to strategically plan our day to be indoors as much as possible because it was HOT!
I'm happy to report that you have a lot of flexibility to reschedule your visit to the Disneyland Resort! The first thing you'll want to check is your
ticket's expiration window. For your 3-day tickets, have you already used any of those three days? If so, then you'll need to use the rest of the ticket within 13 days of first use. If you haven't visited the parks at all with your 3-day tickets then you have a much longer expiration window - likely January 12, 2025, but you can confirm in the original purchase confirmation email you received when you bought them.
Once you've confirmed your expiration window for the tickets, it's just a matter of making a new theme park reservation! In my opinion, the easiest way to do that is through the "My Plans" page on the Disneyland website. To get there from the
Disneyland website's homepage, hover over "My Disneyland" on the right side of the top bar and select "My Plans" from the menu.
If you scroll down on the My Plans page, you'll see your exisiting theme park reservations for later this week. If you click "Manage Reservation" you'll be taken to a page with an option that says "Modify Reservation" next to each reservation date. If you click that option, it will walk you through how to change your reservation dates to a new day that works better for you. Alternatively, if the reservation calendar doesn't go out far enough for when you'd like to visit, then you can just cancel the reservations from that same page and make new
theme park reservations at a later time when you'd like to visit.
I hope that helps, Cindy, but in case you have more questions, feel free to reach out to a Cast Member at the Tickets line who can help you walk through the process over the phone! Thanks again for your question!
Have a Magical Day,
Greg
