The OP never mentioned BCV, the question was about the BWV. Plus...
1) BCV is closer to Epcot than BW by about what, 5 minutes or less. How do you know they wont take the boat to Epcot, making any walking distance irrelevant. You didn't mention that BWV is closer to Hollywood Studios.
2) Don't assume that the OP will have a car, so parking is not an issue. Given their location near the Jersey Shore they will probably fly and use Magical Express.
3) People spend the day walking the parks, but " hiking up a hill to get to the building" is a deal breaker. I assume you don't mind walking up the stairs to your room at OKW assuming you don't have a first floor room, but the hill at BWV is a real problem.
3) Not everyone has an irrational fear of clowns. I also remember you posting that you were not a fan favorite of SAB, so how can you recommend BCV?
