West Wing - as in the movie, it is smaller, dark, great special effects and we enjoy eating there but it's usually crowded and difficult to find a seat. The downside is everyone coming in taking pictures and using flashes. May be scary for young ones.
Ballroom - as in the movie, is the larger room that is beautifully detailed to look like the ballroom. We love sitting by the big windows where the snow is falling down, we find there is less traffic there with folks walking around. We enjoy sitting and looking at all the details especially the murals on the ceiling.
Castle/Rose Gallery - is NOT in the movie and was designed specifically to house the dancing Belle & Beast music box. It is referred to as both. We don't like this room because it's not in the movie, it's very loud & seems very popular with younger kids (maybe to see Belle & Beast) that are also "active". Sat in there once because it was so crowded CM had to seat us and that was all that was available.
I voted that yes the room is important, I do not want to sit in a room that isn't even in the movie.
