Hello, Murphy,
I've been in both and they're each fantastic. The BWVs have been around a bit longer than the BCVs, so minor wear and tear does exist with the BWVs but they're still up to snuff. I'd say choose whichever sounds the best to you -- the theming of the rooms are each unique, BCVs light green, tan, and blues with a New England nautical touch and BWVs much the same with slightly warmer tones in the rooms, and the amenities are the same. I liked the Beach Club Villas just a shade better as I found it quieter (our BWV stay was in a Grand Villa, just above the Boardwalk itself) and closer to my wife's favorite park, Epcot. Either way, you're sure to have a great time.
