Just about a five minute walk if you are really moving or a relaxing ten minute walk although at night you could easily turn it into a long romantic walk as the area is just beautiful. It is also a pretty flat walk in that direction. We stay at the BWI and love to walk around past the Swan/Dolphin, YC/BC and into the International Gateway into Epcot. Lots of folks sit along the boardwalk area between the S/D and Int'l Gateway to watch the fireworks part of the Illumination show. There is also boat service that goes between Epcot, YC/BC, BWI, S/D and MGM. About a 15 minute walk along the waerway will take you right to MGM's front door. You'll love the location. See if you can get a room with a view of Epcot. Also don't forget teh Boardwalk Bakery, Boardwalk Sweets, Flying Fish and all the boardwalk entertainment at night which is just a short walk away from you.
