We LOVE BWV. So much so that we bought additional DVC points there after our original purchase at SSR.
Thoughts: Spending an evening on your balcony is fantastic. Just relax and enjoy the evening. BW Bakery in the morning is a great way to start a day. If you are going to MGM it is almost always quicker to walk through the far end BWV exit and walk there than to walk to the boat dock and pretty much retrace your steps on the boat. If you are coming back from MGM and are on the boat, it is quicker to get off at Swan/Dolphin and walk over the bridge to BW than to ride the boat to BW and walk to your room. Even though the main themed pool is cool, the quiet pools are the best (unless the kids are hung up on the water slide). The community hall is a good way for kids to spend some time away from the parents. If you are anywhere close to a sports fan, an afternoon/evening at the ESPN club is fun (yes it's typical bar food, but it's still a blast).
I could go on for ever, but you get the idea.
