I'm going to go against the majority here and say definitely movies. I've only stayed at ASMu and beforehand there was no question of my choice. DS is a music major, specifically jazz. I asked for and got the jazz building. Then I went to the food court. It was full of teenage and college-aged kids with some very unDisney-like language. And one night, after Enight, when I came back after midnite, way past my usual bedtime, there were so manyolder kids still running around.
But one time I walked over to ASM, just to see what it was like, and it seemed like so much more Disney-like.
