Hello, Stuart! Thanks for bringing your question to the Disney Parks Moms Panel!
The Disneyland Resort is open 365 days a year. So, barring any unforeseen emergency, the parks should be open on Christmas Day 2017. That day also happens to be a very popular day to visit the Disneyland Resort! If you plan to attend that day, I recommend going early and staying as long as you are able.
Also, ensure that you have the
Disneyland Mobile App downloaded before your visit so you can quickly and easily view attraction wait times, make dining reservations, view your
Disney PhotoPass photos, and so much more.
Christmastime is already a magical time of year and spending Christmas at the Disneyland Resort is sure to make that day even more joyous. Follow the
Disney Parks Blog to hear first when they announce details for the
Holidays at the Disneyland Resort in 2017.
Have a great day!
