Epcot Resorts Blvd is a large loop. It runs from a light near the Swan around past the Dolphin, YC, BC/BCV and then past the BW until it runs into Buena Vista Dr again across from the MGM parking lot. Enter the loop from either side depending upon your starting point. From MK and AK, you're better off turning at the Western end of the loop. From DTD, the Eastern end.
