I have stayed at VWL, BCV and BWV so far and have enjoyed all for different reasons. Personally, BCV is my favorite because of its location and the SAB pool. I also like the fact that it is smaller than BWV and has a more intimate feel. I loved VWL as well, however -- that is a very close runner up! The atmosphere is woodsy and beautiful -- and, now that I think of it, if I were going in the winter as you will be, I might choose that because it seems more appropriate for that time of year. When we went to BCV it was very hot and summery, so it was ideal. I guess it all depends on whether or not close proximity to Epcot and MGM matters to you. We loved having so much at our doorstep while staying at BCV, but as I say, the VWL can't be beat for coziness and a rustic, relaxed feel!
Good luck deciding,
Sarah
