Hello, Lance! Welcome to planDisney and thanks for your question!
I am so excited that you are planning a trip to the Disneyland Resort this December!
The Holidays are an absolutely magical time to visit!
As you know, with your Park Hopper tickets, you can begin hopping to the other park at 1:00 p.m. each day. While official park hours aren't yet available for December, I think a good rule of thumb is to plan for the parks to be open form 9:00 a.m. to 9:00 p.m. Then if they open earlier or stay open later, that is just bonus time in the parks during your trip! You'll definitely want to
check the official park hours as your travel dates approach. They are usually released about 30-45 days in advance.
Another thing to keep your eye on as you plan your trip is the
Disney Parks Blog. Not only will the blog be the place where they release all the information about holiday offerings, but sometime in the next few weeks we hope to hear more news about
Disney Genie! Disney Genie will be a great tool for you as you plan your trip because it will create customized itineraries based on your interests. You will also have the option to purchase Disney Genie+ which will allow you to skip most of the queues on select attractions by using the Lightning Lane. Disney Genie is set to be released sometime this fall, so it's likely it will be available for your December trip.
If you have any other questions as you plan your adventure to the Happiest Place on Earth, be sure to stop by planDisney again!
