No Your post was not a complaint, I apologize.
Mine is. I used to work at the fast food in Fantasyland. The first time I experience fireworks as a CM I thought they were bombing the building. Perhaps your theory is true BUT....
I just dont see that as a good reason why they aren't decorating the back of the castle more especially when they are decorating Belle's village area which is much closer. It's just very jarring when the front of the castle is covered in lights and then you walk to the back and there is so little decorations. If not the lights then maybe they can put more decorations on it to make it look more festive.
Sorry I don't think I am getting my point across very well. I just think that as long posters want to have a discussion or offer an explanation to a situation they should be able to.
