December holiday crowds

Good day all,

I’m wondering about the predicted holiday crowds this winter break.
I see an expected steady increase towards the new year, but a predicted drop on 24-25 December according to I am planning a trip over this busy week , (19-27 Dec), and would like to know which days are best. A competing site, (about frogs), has an opposing view that the 24/25 will be 10/10 crowds. Since the price of the “express pass” is higher on these days, it seems Universal is also expecting a very high turn out.
Part of me thinks many will have holiday plans on these days and cause lower crowds, while vacationers like myself would enjoy spending the 25th this way and cause higher crowds.
So far all data I can gather shows this site is wrong.
I need to make a decision.
