Darkbeer, you did a great and accurate job describing the present and past state of DCA. I think DCA might one day really be a "Disney" class park with Lasseter at the helm.
I do have one disagreement with you. You said that the queue for Sourin' is better at WDW. I have to disagree. I was at WDW in December and actually found that, if you can believe it, they spent LESS money on that pre-show. WDW's queue consists of colored plain walls which feature three lighted panels of western scenes. That is it. At least, at DCA there are two walls filled with historic photos of aviation pioneers. I was really disappointed by Orlando's pre-show.
Aviation is such a romantic topic. I can think of so many wonderful ideas for a fantastic pre-show. Sadly, the same top management philosophy that brought us DCA approved WDW's version. Sometimes, less is LESS.
