Hey there, Mengyue! Thanks for stopping by planDisney with your question.
This is a busy week at
Disneyland Resort, as several schools are on a fall break. I am sorry to hear you’re having trouble finding tickets and reservations for October 6.
Although you can purchase tickets once you arrive at
Disneyland Resort, it is subject to availability of
park reservations. The Cast Members at the ticket booth are using the same
reservation availability system that we as Guests are accessing online.
You may want to keep trying online, including the day you’d like to visit. As Guests change plans and cancel reservations to make new ones, their cancelled reservations are released back into the system for other Guests to grab! You might just get lucky.
For next time, I just wanted to mention that reservations can be made 120 days in advance, so as soon as you know your dates, go ahead and try to book them!
Wishing you the very best of luck in securing those tickets and reservations,
Kamini
