The way I read OP is they want to go from OKW to BW in the morning, and from there to Epcot. The replies above would be irrelevant. I can't see how the Epcot Monorail gets involved in any way.
I would say take a bus to HS, then boat or walk to BW, or take Skyliner from HS to Epcot & walk to BW. From BW, just walk to Epcot.
