Just a quick message for the one who did the D23 tour. Did you find the WD Archives a bit too small ?
In fact, there is a huge room behind the one we visited. You can have a glimpse of the HUGE collection on this video shoot by Disneyland paris cast members who visited the lot: Dailymotion - Road Trip USA part 11 - une vidéo Voyages (starting at 13 minutes)
I am dead jealous of their luck. they were allowed to do whetever they want on the entire lot, go inside the soundstages and inside ABC and Feature Animation !
Enjoy the video and get jealous :-) :-)
