While perhaps not the fastest route, another possibility is to take the monorail to the Contemporary, then the boat to WL (it makes a stop at Ft. Wilderness first.) The monorail ride is 5 min and the boat ride is about 15 min. Very pleasant way to go, especially if you have need/desire to stop at the Contemporary first. Coming back from the WL, the boat goes straight to the Contemporary, only a 5 min ride.
