Hmmm....not sure which would be faster. If you go the YC/BC way, depending which door you exit from the Dolphin, you have to actually follow the zig-zag pathway around the contours of the Dolphin before you reach the YC/BC walkway. If you go the BW way, you have to follow the BW around Crescent Lake, then over the bridge to the Epcot walkway. It may actually be the same distance either way.......
