Hey there Matthew,
Welcome back to planDisney and thank you so much for this question! I'm thrilled to see that you're planning a trip to the Disneyland Resort during the
Holiday season this year - I love visiting during this festive time!
I'm glad to hear you were able to get your
park tickets already. I would suggest linking them to your Disney account as soon as you're able so that you'll see them on the
My Plans hub. This page on the Disneyland Resort website is my favorite place to make and manage all the different aspects of my upcoming trips since it has everything all in one place.
You'll need to also make your
theme park reservations for each day you plan to visit, but as you can see on the
Theme Park Reservation Availability Calendar, park reservations are available about six months out from the current date. That means you'll want to check back in June to make those reservations for your trip in December. Since December can be pretty busy at the parks, I would recommend making those park reservations as soon as you're able as they are subject to availability.
Lastly, make sure to keep an eye on the
Disney Parks Blog, especially around the end of summer, to see the details of the upcoming Holiday season at the Disneyland Resort and all the fun extras that will be available to seek out during your visit.
Thanks again for your question, Matthew! I hope you have a wonderful trip to the Happiest Place on Earth.
Have a Magical Day,
Greg
