Hi there Ariana, welcome to planDisney!
You are able to purchase your
theme park tickets on the Disneyland site as well as the
Disneyland app. In the app, you'll want to navigate to the three horizontal bar icon in the bottom right-hand corner, and then tap "Tickets and Passes". You can then tap "Buy Tickets", and your available options will appear. You'll select the number of days you'll want to purchase tickets for, and then also have the opportunity to add the Park Hopper option to your tickets.
The
Park Hopper option allows you access to both
Disneyland Park and
Disney California Adventure Park (subject to park availability) for the date you select. You can hop over to the other park on the same day beginning at 11:00 AM, subject to park capacity. We love adding this option since it is so easy to walk between parks, and then you get to enjoy double the fun!
You will then be prompted to make a
theme park reservation, and you will need a valid theme park ticket and park reservation for each day you plan to visit the parks. Before your purchase your tickets, I do recommend taking a look at the
theme park reservation availability calendar to ensure that there are park reservations available for the dates you'd like to visit.
Once you purchase your tickets, you'll want to explore all of the activities to experience on your upcoming trip! I always like to explore the
dining options throughout the Disneyland Resort, as well as the
Entertainment offerings that we may be interested in. It's never too early in my opinion to start planning out the days of your visits!
I hope this information was helpful for you Ariana. If we can help with anything else for your upcoming trip, please
come back to planDisney!
Have a magical day!
Melissa
