I've stayed at both BCV and BWV in December. However, although I can tell you which one I prefer, please remember-everyone's different. I prefer BCV, partly because the theming appeals to me more, it's closer to Epcot (BWV is more "centered" between Epcot and DS, but I'm not a fan of the Studios). And I like that I can get fast food at BCV without going into "uncovered" outdoors-BC Marketplace is right there, but at BWV, you have to go out and down to the Boardwalk to get a CS meal. But I've never been blown away by a view as I was at the Boardwalk-those BW views are incredible!
