Konnichiwa, Mako San! Welcome to planDisney. I’m so glad you stopped by with your question!
Mako, you will want to plan ahead for your visit, as each Guest requires both a
theme park ticket and
park reservation for each day they’d like to visit the parks. As of now, I do not see
reservations available for December 6, but that can change. As Guests change plans and cancel reservations, those reservations are released back into the system for other Guests to grab. Keep checking the
reservation availability calendar and you may get lucky!
While you can purchase tickets and make reservations in person at the main entrance ticket
booth, the Cast Members there are using the same central reservation system that we access at home as Guests. Your ability to purchase a ticket upon arrival will depend on reservation availability that day.
I know you are coming a long way to Anaheim, and I truly hope you can secure tickets and reservations for your visit. Sending a pinch of pixie dust your way!
Arigato gozaimasu,
Kamini
