Distance-wise, BCV is the closest Epcot resort except for parts of the BC.
They used to allow reservations with Epcot view, but I have heard that they don't take it anymore. Take the woods view, higher floor and you might be able to see Illuminations. There is construction from Soarin' that might block some of the view or make it a less than pretty view.
When you drive up to the BC, the BCV are on your left next to the roadway that continues on under the waterway to Epcot going to the Boardwalk. They are not directly on the water that fronts the BC/YC and BW.
