Crowds Thanksgiving week

Can anyone help me understand the Thanksgiving week calendar. Why is Epcot 9 everyday while MK is 6-7, AK 6-8? DS is a 9 which I get. I realize it will be very busy each week, I just don’t understand why Epcot is projected to be so much more busy than MK. Thanks for any insight you can provide.

This festival typically begins in late November and runs through December, celebrating the holidays around the world with special entertainment and food offerings.
