We (myself, DH, DD6 and DS4) have stayed at AS music in a family suite on our last two trips and been very happy. I have also stayed at AS sports and have looked around AS movies. We are going to AoA in November and staying in a LK family suite. Firstly, cost is a definite difference. Movies does not have suites so you would be in a standard room and the standard rooms at AoA all being in the LM section are obviously not available so it is worth it to consider what you want in terms of room size. We loved having the extra space and extra bathroom at music in the suite and though the layout at AoA is different the amount o space is comparable. From what I have read AoA is head and shoulders above all of the other values in terms of dining, theming and modernity. The pools look amazing and the theming inside and out also looks to be much more immersive into each of the represented movies than AS movies which is limited to a few oversized icons. I am also excited I have a food court with some different and seemingly fresher options. Hope this helps, good luck and enjoy!!
