From Movies:
Walk through Dalmatians and through Mighty Ducks.
You will then be at the "road" between Movies and Music.
Looking back at Ducks after crossing the "Movies/Music Way"(my name for it
).
Looking back at crosswalk for Movies/Music Way
Turning and looking down the sidewalk to Music(all 3 pictures taken from the same spot)
Keep walking straight down the sidewalk pictured above past Melody Hall(do not turn left at the Pool) and then straight through Calypso.
After exiting Calypso,walk across the Parking Lot and you will be at Home Run Hotel at Sports.
Very easy to walk between the 3 All-Stars-we do it all the time-we usually eat at all 3 Food Courts at some point during a trip.
It is an 8-10 minute walk from World Premiere Food Court to Intermission Food Court and an 8-10 minute walk from Intermission to End Zone Food Court.
World Premiere is the "nicest"(design,not necessarily the food) as Movies was the last All-Star built and Disney "plussed" it a little over the identical designs of End Zone and Intermission.
