I noticed this listening to a recording of the Florida ToT attraction, and think it's a rather strange cut. In DCA, just before the drop sequence, when the hotel corridor changes into a starfield and then the projection effects begin, the narration/Rod Serling soundalike has the following lines: "One stormy night long ago, five people stepped through the door of an elevator and into a nightmare. That door is opening once again, but this time it's opening for you." At this point, the drop sequence initiates in time with the visual effect of the elevator at the far end of the hall plunging out of sight.
However, if you ride the attraction in Florida, this segment has several lines not appearing in the DCA show, that I quite like and wish they had as well. They follow thusly, after traveling through the "5th dimension" scene and just before the drops begin: "You are about to discover what lies beyond the fifth dimension, beyond the deepest darkest corner of the imagination, in the Tower of Terror". The narrator delivers this dialogue spot on, and I really do wish DCA had it directly before the drop as well, when the lights go out and it is pitch black for a second before dropping. What say you, Mice Chat public? Would you like to see the DCA version get this extra line of dialogue?
