Hello there, Paula! Welcome to planDisney. We are so glad you are here!
I am so excited to see you are thinking about taking advantage of the
California Resident Ticket Offer. You are correct that at the time of purchase of a multiday ticket, you are required to select all dates and parks for each day. Once you have purchased the ticket you can go back and modify your theme park ticket reservations as many times as you need to until you've used all days or the ticket has expired. Just head to the
Disneyland website and head to the "
Ticket and Reservations Details" page. From there you will click on the option to "Make or Modify Park Reservations". This will take you to a page that shows all upcoming reservations for any ticket linked to your Disney account. This is where you will be able to cancel or modify reservations.
The California Resident Ticket Offer is valid until September 28, 2023. My tip would be to just make sure you have your days planned as far in advance as you can. As you head into the last month, and especially the last weeks, of the ticket offer reservations will become slim or completely gone.
Paula, I hope this helps you feel at ease about purchasing your tickets. Please come back and see us again if you have any other questions for us.
Carrie
