Hey there, Amanda! Welcome to planDisney. I would be anxious to start reserving park dates and start planning your upcoming trip too!
Currently, theme park ticket reservations can be booked up to 120 days in advance. The
Theme Park Reservation Availability Calendar usually opens up one day at a time or a few days at a time, but not the whole month. So if you are booking multiple days of a trip, you will most likely want to book them day by day so you can be sure you get your day and park you wish. Lately, days haven't filled up too quickly, but December is a peak time when people are wanting to visit during the holiday time.
Speaking of holiday time, you will be there to enjoy the decor, attraction overlays, and special happenings since you will be there in December! We have gotten a teaser of what is returning and happening, but more information will be released as we get through Halloween. One of my favorite holiday-time happenings at the parks is the
Disney Festival of the Holidays at Disney California Adventure Park. Our family loves grabbing a Sip and Savor Pass to grab a handful of bites and hang out and listen to some of the musical entertainment going on over at Sonoma Terrace.
Amanda, I hope you are able to secure the parks and dates you are hoping for! Please come back and see us again if you have any other questions along the way!
