It's been discussed before about what kinds of major changes might be made to any of the rides in WDW, but what sort of relatively minor ones would you feel would improve the rides?
One thing that comes to mind would be a suggestion of having the doom buggies of the Haunted Mansion move through a pitch black room, as it does so, suddenly at various times a flash of light would appear either over your car, on the side, or directly in front as if the "ghosts" were surrounding you. And perhaps some quick gusts of wind would come out of the back of the seat as they did this, to make the hairs on the back of your next stand up.
