Would xmas weekend be as packed as new years weekend?

so we have been many times before including once around xmas time in 2013 went 18-21. The calendar said it was “forget about it” packed. For us it was great until noon then it was kind of packed then after 8 pm we could not even exit from all the crowds. But given hat it was xmas weekend we thought it was manageable. The only difference this time is we are taking another child ( 6 years old) who has never been. We will not be doing fantasmic or parades maybe WOC. Can we do it?
