DD30 and I stayed at ASMusic this summer in room 3601 of the Rock Inn. We really enjoyed the view out the window and there was a pool in easy walking distance. I have stayed at both Music and Movies several times, and I have to say that we don't mine the AllStars at all. There is a queen bed and a queen murphy bed in each room, and yes, the murphy bed is comfortable; I slept on it several nights and it has a better mattress than what we have at home. The resorts are smaller, so it is faster/easier on the feet when you get back from your long park days, and there is plenty of variety in the food court if you want a meal at your hotel. Honestly, if budget is of concern, the AllStars are a pretty decent choice for Disney accommodations.
People talk about the convenience of the Skyliner, and while we love riding it, it's not all that. IF there is thunder in the area (I think they look at at 10mile radius, a CM said) the Skyliner shuts down. There is often a change involved depending on the route, and when we were there in August they were putting more than one travel group into each cab and asking people to fold strollers for more space. We enjoy riding the skyliner, but it isn't a big factor in our choice of resort. IMO, most Disney resort rooms are on par with the EconoLodge to the Hampton Inn; what you are paying big bucks for is the additional amenities. For example, our kids were happy in any pool, so an over the top pool with a slide wasn't a big draw for us. Personally, we choose AllStars pretty frequently when we stay onsite, with Music being our favorite.
