On one of the mapping thingys online (think it was Google Maps) you can get the walking distance from one attraction to another.... well at least I could do this for Epcot.
You get the name for the attraction by hovering your cursor over it. (I did France Pavillion) then type that in the open box on the left. Select the walking icon and "get directions". Do the same with your chosen destination (For me it was TT). It will show you the route and the approx walking time.
You might have to play around with it a bit... for ex, it kept auto-changing my origin point from France Pavillion to the service road that runs behind the pavillion.
