Hello there, Ashley, and welcome to planDisney! It sounds like you are doing everything I typically recommend for people visiting the Disneyland Resort - it's never too early to start planning your trip!
You're definitely correct that you will need to make a
theme park reservation for each day of your trip, but as of when I'm writing this response, it looks like the Disneyland Resort has only opened reservations through the end of June 2023. I will say that this is totally normal, though! They open up the reservation availability about 4 months out from the current date. My recommendation would be to bookmark the
theme park availability calendar page and start checking back in summer.
I would also highly recommend keeping an eye on the
Disney Parks Blog around that time as well for more information on
Halloween time at the Disneyland Resort and news on this year's
Oogie Boogie Bash - A Disney Halloween Party! I've never had the chance to attend any of these special events, but wow do they look incredible! If they offered this special event on one of the nights of your visit, you would need to purchase
special event tickets to attend, so again, the best place to get information on that is the Disney Parks Blog.
As we get closer to your vacation, I'm sure you will have more planning questions, and we here at planDisney are here to help! Please feel free to come back and see us with any of those follow-up questions. Thanks so much for stopping by, Ashley!
Have a Magical Day,
Greg
