I believe the parks and resorts will be "In Progress" when
MVMCP starts (first MVMCP is 11/8). All the Halloween decorations are down by 11/2 and the Xmas decorations start going up the next day. If you have ever seen the HGTV special on Disney Christmas decorations, the whole process is quite impressive.
HERE is part 1
As for the EPCOT storytellers, they are a great show. I haven't seen them all, but am impressed by what I've seen so far. They start 11/23.
