I haven't been at Halloween, but have doing research for our trip coming up next month. FRom what everyone says, it looks like it will be more crowded than it is now (IOW... not dead). But less crowded than mid-October. I am anticipating low lines except for those times we choose to do an evening EMH (only one of those to deal with). We are used to going at busier times, so I think the last week of October is going to be a treat for our family
