Hi Cindy,
Thanks for bringing your question to planDisney!
I love that you are thinking about park hopping between
Disneyland Park and
Disney California Adventure Park when you visit the
Disneyland Resort.
To visit each of the Disneyland Resort theme parks in the same day, Cindy, you'll want to
purchase a Park Hopper Ticket.
When you visit a Disneyland Resort theme park, you'll need both a valid theme park admission and a valid theme park reservation for the same day.
When you
purchase new theme park tickets, you'll be able to both purchase theme park tickets and make theme park reservations at the same time. When you make your ticket selections during the ticket purchasing process, you'll be prompted to select your ticket type. This is the step in the process where you would choose either the One Park Per Day ticket type or the Park Hopper ticket type. With a Park Hopper ticket type, you would begin your theme park day in the park for which you made a reservation, and then you could visit the other theme park after 1 p.m. You could also hop back and forth between the parks until their closing times. Keep in mind that park capacity limitations will determine the ability to park hop.
Cindy, I hope you have an opportunity to make park hopping a part of your Disneyland Resort theme park plans. There's always so much magic to enjoy at each theme park, and park hopping is a great way to add even more magic to your day!
Jerry
