Hi Karen!
Thanks for bringing this question to planDisney!
The
Hours & Events Calendar updates about 2 months in advance. So, for your trip in early December, you should be able to see the park hours by early October.
The Hours & Events Calendar link provided above will also show you
Early Entry and
Extended Evening Hours, any after-hours events, parade and nighttime showtimes, and attractions that are closed for refurbishment.
You’ll also be able to find park hours in your
My Disney Experience app. On the homepage, scroll down until you see the current date’s park hours. In that section, click All Hours, then find the date of your trip on the calendar.
It’s good to note that park hours and showtimes are always subject to change. So, I like to use the listed park hours as guidance a couple of months before my trip, but I always recheck the hours as my trip gets closer.
Of course, if a park is hosting a holiday party, you can expect the park to close early to regular park guests on that night. During the date range you provided, Magic Kingdom will be hosting
Mickey’s Very Merry Christmas Party on December 2nd, 4th, 5th, and 7th. And Hollywood Studios will be hosting
Jollywood Nights on December 1st and 6th.
I hope that helps as you continue to plan your trip! If you have any other questions, feel free to come back and visit us.
