Hi Christina!
Thank you for bringing your question to the Disney Parks Moms Panel!
A trip to
Walt Disney World is great any time of the year, but I also like to try to plan trips for when the parks will be less crowded.
It may be surprising to know that the dates you mentioned are predicted to be fairly busy. I believe it's due to a holiday falling on that Monday and many families taking advantage of a long weekend with their kids.
There are many crowd calendar trackers on the internet, but my favorite is at touringplans.com. Right now, they predict crowds to be between an 8 - 10 (with 10 being the highest level) for January 13 - 18. Of course, this is just an estimate and is subject to change, but they are usually fairly accurate in their predictions.
I hope this helps you with your plans! Please let me know if you have any other questions.
