Hi Alon! Thanks for visiting planDisney.
Adding more days to your trip sounds like a recipe for fun! And it should be an easy adjustment to make ahead of time after you've purchased your admission tickets online. Most of these upgrades can be made over the phone, so you'll want to give the
Tickets phone line a call to add an extra day. A friendly Cast Member should be able to assist you in adding a day to your existing valid
admission ticket. Have your ticket ID numbers handy as well as your method of payment.
There's a chance the Cast Member won't be able to make the
theme park reservations for you, and in addition to admission tickets, all Guests do need a theme park reservation to enter the parks. If they can't do it for you, you can make those reservations for yourself online provided they are available. To do so, navigate to the Disneyland Resort website, hover over "My Disneyland," and select "Ticket and Reservation Details." On the next page, scroll down to "Make or Modify Reservations" to begin the process of securing theme park reservations for your additional park days.
If your preferred day isn't available,
keep checking! While availability is not guaranteed, it does sometimes change. When Guests cancel their plans, availability reflects that and it's possible to secure a theme park reservation. I suggest checking throughout the day to increase your chances of grabbing a newly available reservation. I'll keep my fingers crossed for you!
Have a magical day.
Elizabeth
