Mansion needs to be down for more than a couple of days, unfortunately. It's getting kinda dire. I'm not sure how modern WDI can go through there with their checklists and deem it show-worthy. It functions, but it doesn't look great. The walls in the stretching rooms are in a terrible state, the Doom Buggies make a racket that sounds like chains at the load and unload areas, Leota's floating objects and the ghouls in the graveyard all need to be repainted so you can actually see them, the ceiling tiles in the seance room need to be replaced, the boundless limbo of mist and decay and staircase at the start of the ride need a permanent fix so it doesn't look like a big warehouse (I'm like 99% sure it wasn't always that bright), the pop-ups need to be faster and I'm still not satisfied with the lighting in the ballroom. Perhaps those figures need to be refreshed as well. It seems like maintenance of the classic version of the ride has been neglected, with no serious refurb in years.
I suppose all we'll be getting is some version of the Hatbox Ghost, which I'm praying is on model.
As for Star Wars in DL, the fact is they don't NEED to add any attractions. The most I see them doing is plugging the new movies with previews, props, character meet and greets and maybe updates to Star Tours.
