Hi Leah!
How exciting that you are planning a trip to
Disneyland!
Halloween Time at Disneyland is so much fun! I am especially excited about the
Haunted Mansion Holiday celebration and seeing the decor from The Nightmare Before Christmas!
Leah, you will be happy to hear that when you purchase your
theme park tickets, you can choose to visit
Disneyland Park or
Disney's California Adventure Park. You do not need a park hopper ticket to spend separate days at these parks. You would only need to use the park hopper option if you were to visit both Disneyland Park and Disney's California Adventure Park on the same day.
If you happen to change your mind and decide to add the park hopper option, you can do so at the main entrance when you arrive. You will just need to pay the difference between the cost of your ticket and the cost of the park hopper option.
Park choice is subject to availability, which you can determine via the
theme park reservation availability calendar. You can also see if the park hopper option is available on the days you want to visit by reviewing the calendar. After you purchase your tickets, you can make your
theme park reservations.
Please let me know if you have any other questions and I'm happy to help!
Magically,
Stacy
