Hi there Elizabeth,
Welcome to planDisney, Happy New Year, and thank you for your question!
How exciting that you'll get to spend the weekend celebrating the new year at the Disneyland Resort! I'm sure you'll be making some amazing new magical memories with your family during your trip.
You'll get to experience double the fun as well since you'll have the chance to see all of the holiday season festivities like
A Christmas Fantasy Parade and
"Believe...In Holiday Magic" Fireworks Spectacular on your first day, and then join in the new year festivities on your second day!
The best places to stay updated on what to expect over the weekend would be the
Disneyland mobile app (specifically check the Map tab and filter for Entertainment) and the
Hours & Events Calendar on the Disneyland Resort website. These will be your two best bets to see what's been announced so far to help plan your visit.
Additionally, you could check the
Disney Parks Blog - while there haven't been any articles posted yet, it's possible they could post something between now and New Year's Eve.
Thanks again for your question, Elizabeth! I hope you and your family have such a fun time during your trip. It's likely to be pretty busy, so make sure to take your time and enjoy being in the Happiest Place on Earth.
Have a Magical Day,
Greg
