Yeah, AS Movies often has a slightly higher rate because more families with kids tend to want to book there due to the themed areas ( Toy Story and Dalmatians being a big draw for little ones ).
It has a smaller ( but nice ) food court when compared to the other two All Star Resorts.
All Star Sports draws a LOT of bookings from tour groups, visiting school groups, school teams, cheerleaders, and *jock* Dads with families.
In January, Sports can be jumping with waves of tour group folks or visiting teen groups.
You have been warned!
I personally love All Star Music out of the clutch.
Of the three, it has the least amount of families with children so i find it to have a much mellower vibe.
It also has a more straightforward layout compared to the other two, in that the pathways are more of a *straight walk* from point A to point B.
I find Sports and Movies walkways tend to be more curvy and lengthy from point to point.
I would rather walk from the main lobby to my room in as straight a path as possible after being on my feet all day walking the Parks, instead of taking the meandering *scenic route* by the pool(s) and giant figures late at night.
Those steps saved make all the difference when you are tired from a long day !
Hope this helps !
