Honestly, I just don't see it happening, since Disney has suspended all of the things that gather crowds, and therefore make the special parties special (fireworks, parades, castle shows), and they probably wouldn't want CMs and guests in close contact receiving cookies and treats. Plus with the whole actors equity union issue, it would be hard to run the party. Decorations will definitely go up but unfortunately I don't see any Christmas activities happening this year at WDW
