Disneyhead (p. 719, old thread):
OK, those concerned about there being no moving staircase. If you notice in the pic of the Portrait Hall there are at least 2 staircases that start halfway up the wall. That is obviously the room where the moving staircase is. Now, if the staircases will actually move. Who knows.
And yes Butterbeer is carbonated. In the video of them sampling it it has a frothy head like regular beer. And that doesn't mean it can't be frozen. 7-11's Slurpees are carbonated.
And don't quote me on this, but I made a quick drawing on how I believe they will be using the smaller domed screens (based on what I have heard and a drawing posted earlier in this thread). I believe, based on the info released in the past 10 hours there will be 2 of these systems seperated by the scenes with the full sized AAs. One at the beginning right after you fly out of the RoR to join the Quidditch match and one at the end where you rejoin the Quidditch match.
