there is no reason to believe Walt would abadone his creedo, his desire to keep his park clean and all the attractions looking prestine. it is a very safe assumption to assume that would transfer over to any park he opened. and it is safe to assume that since he said he wanted his team to handle the outside and ghosts to handle the inside of the ride and that has been continued for decades after his death in Disneyland that had he had been around for WDW's mansion and he had extended that credo it would have been carried out to this day. but he died before it opened. WED did have FL's mansion looking beautiful when it opened but the powers that be did not keep that tradition going since walt was not around to express his wishes , so team Disney Orlando let the mansion look how it does now because " it is the haunted house spooky ride and the haunted house needs to look spooky. why doesn't it look spooky?? we want it spooky."
