Just back today from a 5 night at BWV's and 4 nights at VWL. For us, BWV's beat VWL hands down.
We went over to BCV's a couple times and we may do a 50 point addon there to get SAB(3 year old has sand on her mind), but for us BWV's seemed like a complete resort where the villas are the predominate unitswith the inn side seeming to be secondary. At Beach Club its the opposite, the Yacht and Beach Club resorts dominate, while the Villas are added on in the back. There isn't really a central places of activity that takes place in the evenings.
At the BWV's we watched Illuminations nightly from our BWV room(3rd floor on BW), went to ESPN a couple nights, strolled along the BW, shopped, watched some shows, then retired to the room with a 2 minute walk. We had almost no noise from the room even though we were only on the 3rd floor. Great stay.
The main lobby of both places was quiet, while VWL was easily the noisiest, but in a good way.
