Howdy, Diane!
A very warm welcome to planDisney! Thanks for stopping by with a question!
Wanting to extend your trip to the
Disneyland Resort before you’ve even arrived? I’ve certainly been there before! To upgrade your 1-Day Theme Park ticket to 2 days, you will have to make this change at the Disneyland Resort Main Entrance Ticket Booth. Please note this upgrade is subject to availability. I recommend checking the
Availability Calendar to see if there is availability at your desired starting theme park on your extension date. If an upgrade is available, a Cast Member will assist you in person.
If you don’t currently hold a park hopper ticket, you can make this upgrade at the Main Entrance Ticket Booth as well. It will allow you to hop to the other theme park after 1:00 p.m. You don't need to make an additional
Theme Park Reservation to hop to the other park. And you are able to hop back and forth between parks during Park Hopper hours, subject to theme park capacity.
I hope this helps! Thanks again for bringing your question to us here at planDisney!
