Late Jan crowds

My fam might be in Orlando in late Jan. I was surprised to see how high the projected crowd levels are (Jan 22-26, CL 6-8). We’ve usually been in mid Nov when crowds are quite low. Any idea what’s driving the higher CL? It seems early for Celebration of HP. Thanks!

The ‘Celebration of Harry Potter’ event is happening from January 27-29 so maybe that could have something to do with it.
