The boat travels from International Gateway from Epcot to BW, then to YC/BC, then to S/D, then to MGM; takes about 35 to 40 minutes. Coming back from MGM takes the same time as it does the same stops in opposite order (S/D, then YC/BC, then BW, then Epcot). Walk from Epcot to MGM takes about 25 to 30 minutes normal pace. Fastest way is to walk from Epcot to S/D boat dock (10 minutes) and take boat from there to MGM (8 minutes).
