Hello, David!
Welcome to
planDisney, we are more than happy to help get your
Theme Park Reservation days sorted out.
Depending on when you're visiting, I recommend taking a look at the
Availability before making any changes to your current plans. What you will have to do, to switch your days, is cancel your first reservations and then reschedule your reservations as new ones. You will repeat the reservation scheduling process that you originally did when you first made the reservations.
I know it can be nerve-wracking to cancel and reschedule, but as long as there’s availability, you should be fine to do so. I’ve done this a few times with my
Walt Disney World Resort reservations. I just make sure my fingers are quick, which as long as you complete the change within a couple of minutes, you should be just fine. David, keep in mind reservations are subject to availability so as long as there’s availability the changes should be a breeze.
After completing the switch, I recommend signing out and back into your
Disney account to make sure the changes are there. You should see your park reservations on the home screen of the
Disneyland mobile app as well, so you can also check there!
David, I hope this helps complete the switch. If you have any other questions, you know where to find us!
