I was checking out Google Earth, and the Hess by Boardwalk seems to be relatively pedestrian friendly, as long as you cross Epcot Resorts Blvd @ the crosswalk up at E. Buena Vista Dr instead of dashing across 6! lanes on traffic! (there are 2 driveways to Hess, one on each road Be safe! Walk the extra 500 ft or so on the sidewalk!)
If you go to Google Earth, just copy and paste these co-ordinates into the search box:
28°21'51.35"N 81°33'7.58"W
You can see the sidewalk from DVC & BW front entrance to the outermost parking lot and it continues along Epcot Resorts Blvd to the intersection with East Buena Vista Dr,
-- across Epcot Resorts Blvd (striped crosswalk and all!)
-- right to the turnoff for Hess off E Buena Vista Rd )in fact, the sidewalk continues up to the Reedy Creek Emergency/Fire Station.
So, careful walking up the Hess driveway!
