I was there yesterday (19th) and I saw that black paper stuff. I couldn't figure out what is was for. I thought they busted a window or something when they were working on it lol. I actually got a backstage tour of the castle led by myself on Friday night. It was after Wishes and most of the park had cleared out. I asked if I could go take some pix from Cinderella's Royal Table and they let me. So I went out the exit doors that went to the balcony on the back of CC, then I walked around up there for a bit. It was a spectacular view. There was a metal gate towards the side/front of the castle that was open. I read the sign on the gate...it said "DANGER! Fireworks! Do not open during operating hours!" but I didn't open it...it was already open! I figured it wasn't dangerous any more since Wishes had already been shot, so I started going up the set of like 5 steps right after the gate, but I decided I better not in case they had security or something. The backs of the towers (short ones on the outside wall) all have doors on the back of them, so I pulled on the handel and both of them opened! I didn't go in them, but it looked like a construction storage area. I figured, maybe, if I had more time, I could have figured out the path to get to the top Spire where Tink flies from. But I didn't. If you want a great view of Tomorrowland or any other land for that matter, I say you should try this! I have some pics of the castle from there and a view of Tomorrowland. I plan to get a website and fill it with the 600 pics that I took. I will post it if I end up doing this!
I'd love to see them too - whenever you get the chance!
