Yep, when I was there right before the first MNSSHP in 2019 they decorated mid trip. I was there one night for fireworks with no decorations, came back the next morning (I think it was one of those early morning events, but I’m getting old and can’t remember, but it was early lol) and *BOOM* it was Halloween
I don’t think the Halloween decorations will be as much this year since they will have to put up 50th Anniversary decorations.
