I own at BWV. Last Aug, we decided to try BCV because it was brand new. Our 1 bedroom was beautiful, and we really enjoyed our stay. It was hot, so we got to use Stormalong Bay a few times also.
That said, for me, I prefer the atmosphere at the Boardwalk. BCV is very quiet and peaceful at night. BWV always has something happening within an easy walk.
As far as the room, I preferred the bathroom layout at BWV. Our 1 bedroom at BCV had the large bath area with jacuzzi tub and sink. Then in a separate room was the shower and sink. Off of that room, there was another tiny room with the toilet. BWV only had 2 areas....jacuzzi and sink, and then other room with shower, sink, and toilet.
Really, both resorts are beautiful. If you have stayed at all the others, I'd definitely give BCV a try.....I don't think you will regret it.
