Okay, just got home from DL, and here's my take on it!
Personally, I think WDW and DCA are dead even in my book. Each has its pros and cons.
WDW's outdoor queue area beats DCA's hands down. One thing I noticed right off the bat about DCA's queue is there is a large section (right next to the building, the switchbacks, for those who have been on it already) of the queue that has next to no shade, no fans, and no misters. Methinks they will see a LOT of cranky, hot guests waiting there this summer.
DCA's boiler room area beats WDW's hands down. I walked into there and was CREEPED OUT. There's one boiler that looks to me like a big face, and it was creepy.
The two stories also makes it feel more cavernous.
In the SFX department, I call it a tie. The little ghosts segment is very similar on both (DCA uses the elevator rather than a window). Where WDW has the horizontal movement (which I personally have never found that impressive, but that's just me), DCA has the mirror effect, which was pretty well done.
As for the ride sequence... well, DCA's definitely caught me by surprise! I was dropped when I wasn't expecting it at all at one point. Overall, I'd call them pretty even here, too.
Now, as to this whole voice over debate... do you mean the video in the library? It seemed to me to be the EXACT SAME video as at WDW, just with DCA's tower inserted into the exterior shots rather than WDW's tower. As to the narration in the tower... well, it certainly never struck me as being bad. Sounded great to me!
I have to agree - don't just judge something by a video. Seeing it on video and experiencing it yourself are two VERY different things. Don't knock it til you've tried it.
I also have a few photos up that I took at
