We just spent 7 days at BCV and 3 days at BWV this past October. Since we stayed at BCV first, and had excellent CM service, and BWV second, and had several CM issues, we clearly preferred BCV over BWV. If things were a little more even, like the service, we probably would have still preferred BCV, but none of my family will stay at BWV anytime soon.
Are biggest issue with BWV was the main pool being closed, but no one told us we could use SAB, that there was a shuttle to take you over there, or that the quiet pool in BWV was open.
We didn't like the long hallway walk, but I don't think it was that bad, except for the days we went to Hollywood Studios, were you basically backtracked. If we didn't have a stroller I would have gone down the stairs near our room. I think they should have put an elevator near the quiet pool.
The other thing I didn't like where you had to go to fill-up your refillable mugs, aside from coffee in the morning you had to go all the way out to the boardwalk. That is when the long walk bothered me.
At BCV, I do agree that it is a long walk to the pool (at least the drinks were close) and I though the selection at the inside counter service was just okay. (We've been spoiled by SSR, I think it is the best of the
DVC resorts.)
To me the two big things BWV has going for it is the "std room", which can save you a few points, as has been mentioned. But the second, which I'm surprised hasn't been mentioned already is that BWV has three bedroom grand villas and BCV doesn't. I think that is a big ommision over at BCV.
In the end, as many have said it is personal choice, and I'd give BWV another try, we didn't like OKW too much when we first went, but it is was better the second time.
(BWV Pros, if you have observations/suggestions on the refillable mug, or better ways to get to Hollywood let me know! I'm all ears!! lol)
