Hey Victoria!
Welcome to
planDisney!
What an amazing gift you have received from your friend! The gift of Disney is always a good idea and your friend sure knows the way to your heart. If the ticket is an unused whole ticket then you can certainly use it. In the past, tickets were not assigned until you got to the turnstiles where a Cast Member then took your picture and assigned the ticket. We are still waiting on more information as to how previously purchased tickets will work with the new reservation system. If I were you, I would call
Ticket Services to get it changed and linked to your Disney account either on the
Disneyland Mobile App or
Disneyland.com so it's ready when it’s time to make a theme park reservation.
With the reopening of Disneyland Park and Disney California Adventure Park on April 30, 2021, there are some restrictions that were issued from the state in the theme park reopening guidelines. When large theme parks reopen like the ones at the Disneyland Resort, it will only be available to California Residents. I see you're from Arizona so I just wanted to let you know in case you were not aware. It won’t be forever but keep that in mind when planning your next trip.
Well Victoria, I hope this information finds you well and let us know if you have any other questions.
Remember, always believe in the Magic!
Andres
