Hey there Kristin,
Welcome to planDisney and thanks so much for your question! Early January is such a great time to visit the Disneyland Resort as, from my experience, there
tend to be lighter crowds and the weather is usually fantastic. You're going to have so much fun!
The best way to keep an eye on exactly what will be closed for refurbishment during your visit is by checking the
Daily Events Schedule. This schedule shows up to about six weeks ahead, so you've still got some time until your visit dates show up, but it will show any planned closures as well as planned entertainment for each day. I like to switch to the 5-Day View option by clicking the toggle near the top right of that page to see my entire visit on one page.
While there haven't been any official construction dates shared, yet, the Disney Parks Blog did share recently about an
expansion to the area around Haunted Mansion coming in 2024. No word on exactly when this will kick off or how it might impact access to the attraction, but the Daily Event Schedule and the
Disney Parks Blog are the two best places to stay updated with all the news from around the resort.
Regardless of what is closed for refurbishment during your visit, I'm sure you're going to have an amazing time visiting the Happiest Place on Earth, Kristin. Thanks again for your question and make sure to come back and see us if you think of any follow-ups as you get closer to your trip.
Have a Magical Day,
Greg
