We were in the parks last year from 10/31 thru 11/11. We went to the last MNSSHP on 11/1 and when we went into MK on 11/2, it was Christmas. As to the rest of the parks: Epcot was still very much decorated for the Food and Wine Festival, so we didn't see any Christmas decorations there. We saw some things in some of the shops in HS, but it was mostly just a few window displays and merchandise if I remember correctly. I don't remember seeing anything at all in AK. And in our resort (Pop) there was a big display of Christmas themed merchandise in the gift shop, but no other decorations.
I would guess that during your stay, you will see the Christmas theme becoming more obvious each day.
