I am a big fan of the BCV.
I liked BWV too, I think I would go there again if I was with little kids who would like the Clown Pool.
But I have been spoiled and love the sand bottom Storm Along Bay, and the little lazy river "pool noodle" ride section.
If it isn't about pools or being right on top of EPCOT, and you love walking a lot, BWV is still a great choice. I agree, it is not close enough to DHS to make a difference in my opinion, take the boat if you hate walking to either Park.
However BCV is steps away from the International Gate of EPCOT and you will get there faster and come back faster to BCV, and be in your room faster, then if you stayed at BWV. In general the hallways at BCV are shorter typical walks than those at BWV.
If you have a car, Parking at BWV is awful without paying for Valet Parking.
Parking at the BCV is pretty decent.
I prefer the interior design and decor of the BWV to that of the BCV, but it isn't enough for me to give up my love of the BCV.
