100% just a guess, but I’m guessing the setup in that room was expensive and involved, and on the one hand they’re loath to destroy it, but on the other, both iterations of that attraction apparently deserved their own slide whistle sound effect when graphing guest satisfaction scores. Also the footprint is quite small so it’s not like you could replace it with a dark ride. It was probably low priority, a weird space to work in, and there was possibly hand wringing about whether or not to salvage anything from the bones of the original setup.
