Hey there Connie,
Welcome to planDisney and thank you for your question! I'm thrilled to hear that you're planning a trip to the Happiest Place on Earth early next year! It'll be here before you know it.
January is typically a great time to visit the Disneyland Resort if you're hoping for lighter crowds - though from my experience, that can also come with some attractions also being down for refurbishment.
However, your best bet will be to keep an eye on the
Hours & Events Schedule as it becomes available for the dates of your visit about six weeks prior. This page shows planned park hours, entertainment schedules, and attractions that will be closed for refurbishment - the latter of which you can find near the bottom of the page in a section you can click to expand and see the details.
There haven't been any official announcements yet for that time, so this page will be the place to check once the schedule is available. However, even if there are attractions down for refurbishment, there will still be plenty of fun to be had! You can also check the
Disney Parks Blog to see if there are any additional fun opportunities happening around the Happiest Place on Earth during your visit.
Thanks again for your question, Connie! I hope you have a great time during your upcoming trip.
Have a Magical Day,
Greg
