When I go solo my favorite is All-Star Music.
Music is laid out like a giant guitar, and the bottom end is mighty far from Melody Hall, which houses the bus stops and food court. But I always rent a car, so I request a building in the Broadway section, which is far away, but close to the parking lot, and in the morning I simply drive around to Melody Hall for breakfast.
Since it's so far away from both Melody Hall and the pools, Broadway is very quiet and peaceful.
Fortunately, the experience that SimbasMom had with obnoxious college kids is not common. In all of my stays at ASMU I have never had any similar experiences; I have also never been near any loud tour groups or had any trouble getting a good night's sleep at ASMU. And despite what others may have experienced, I cannot hear toilets in neighboring rooms flushing when I stay at ASMU.
One small problem I had with ASMU once: I was in Broadway Building 8, on the side directly facing Jazz Inn Building 9. If you
look at the map of ASMU, you can see a paved path running between Bldgs 8 and 9; this path is used as a service road by gas-powered stretch-limo golf carts which drop off the MouseKeeping staff every morning at 8am. Now, I know many DISers are early risers when at WDW, but I like to sleep in, and I was not happy to be jarred awake every morning by the sound of go-carts 25 feet outside my room! It was a lot like being awakened by a rude neighbor who decides to mow his lawn with a big loud riding mower at 8am on Saturday morning - so avoid the sides of Bldgs 8 and 9 which face each other.
