Hello there Zara! Welcome to planDisney, we're so glad you're here!
I'm sorry you're having trouble purchasing theme park tickets to the Disneyland Resort. The
Australian Disneyland site does recommend that you work with a local travel agent to help book your visit. I'm sure a local travel agent who specializes in trips to the "Happiest Place on Earth" will be such a great resource to help ensure a smooth trip to the States for you and your family!
You are correct that you'll need to secure a
theme park reservation to go along with your valid theme park ticket for each day that you'll want to visit Disneyland Park or Disney California Adventure Park. You may want to explore adding the
Park Hopper option to your tickets as well so you can enjoy your favorite attractions and entertainment in both parks in the same day! Both parks are located so close together, it's very easy to hop between both parks, we usually crossover several times a day during our visit.
It looks like you'll also be visiting during
Halloween Time! It's one of our favorite times of year to visit, one of the best things about this seasonal celebration are the overlays on certain attractions such as the transformation to
Haunted Mansion Holiday and
Guardians of the Galaxy - Monsters After Dark. Two of our favorite attractions have been transformed for the Halloween season, and it's so fun to experience new versions of both!
I'm sending you all of the pixie dust that you're able to secure your theme park tickets soon, Zara! If we can help with any other planning questions for your holiday,
please come back and ask!
Have a magical day!
Melissa
