Hi there and welcome to planDisney, Sheila. Thanks for dropping by to share this question with us. Hooray! Your visit to the Disneyland Resort is almost here and I'm thrilled to help out.
One of the things that I love about Disneyland Resort theme park tickets is the flexibility that is built into them. I peeked at the
Theme Park Reservation Availability calendar and noticed that most, if not all, dates in March are available for both One Park Per Day tickets and Park Hopper tickets. This is getting curiouser and curiouser, but after putting on my thinking cap, I'm wondering if perhaps you are using two separate 1-day park tickets.
1-day tickets are tiered and can be used on any date in the designated tier (or lower tiers) through the expiration date of the ticket. It may be that the dates that you are trying to switch your visit to are designated for higher-tiered tickets.
You can check your ticket tier in the
Disneyland app by tapping the "☰" to open the menu, followed by tapping the "Tickets and Passes" tile. In the colored bar above your ticket's barcode, you will see which tier type your ticket is. Just below your ticket, you will also see a blockout calendar that will show you which days you can use your specific ticket.
If there's a date that you would like to visit that is blocked out based on your tiered ticket, you do have the option to upgrade your ticket to the higher tier.
Any wholly unused ticket can be applied toward the purchase of a new theme park ticket as long as the price of the new ticket is equal to or greater than the price of the original ticket. For help with upgrading your ticket, you can reach out to a friendly Cast Member at the
Tickets phone line for assistance.
Unless you think you still might visit the theme parks on your confirmed reservation dates, you won't need to hold on to those theme park reservations and can cancel them when you're ready. To cancel, visit the Disneyland site and click on "Ticket and Reservation Details" found under the heading "My Disneyland," followed by "Make or Modify Park Reservations." Here you will find your theme park reservations and a link to "Cancel Reservation." Once canceled, your tickets can still be used through their expiration date.
Sheila, I hope this helps and gets to the bottom of things. Most of all, I hope everything gets sorted and that you are able to find some time to visit the Happiest Place on Earth soon! If I've completely missed the mark with your question, don't hesitate to come back and ask us another one. Here's hoping that everything works out!
Have a magical day,
Michelle
