Question about Xmas crowds?

[Whitegloves]

I know that the MK is crowded on Christmas Day but what about the other parks? How crowded is MK on Christmas Eve?

All the parks will be extremely busy the entire week.

At that time of year your best bet is the EMH, fastpass, then find something else to do the rest of the day(plenty of fun at resorts).
