We originally purchased at BWV, and sold it to buy BCV. We love it there! Stormalong Bay is amazing. Movies and s'mores on the beach is really nice. Parking is MUCH better, and the rooms are MUCH closer.
There are other differences as well, but not so important. As far as views, we always got a swan/dolphin view at BWV, and we think those hotels are the ugliest things ever. We much prefer the views at BCV. The courtyard view is gorgeous, the quiet pool view is okay...but we love the woods view, and consider it a great bonus if we can watch Illuminations. We like the food options at BCV better. The Marketplace carries more grocery items than the Screen Door, so if we have to stay at BWV, we often walk to the Marketplace to buy our groceries. I love the salads, pizzas, and sandwiches they make in the Marketplace. Between that, Hurricane Hannah's and B&C, we are set! I get grumpy when I am at BWV, need something from the Screen Door, and it is raining. We tend to go to our room on rainy days, but love being able to go easily between BCV and the hotel. When we drive, we usually bring a volleyball, and play some games on the sand court. And with the back entrance into the villas, you are super close to Epcot. The walk to HS is MUCH shorter from BWV, but we always take the boat there.
Of course, BWV is always our second choice if we cannot get into BCV. It is a beautiful resort as well....we just like BCV better.
You really cannot go wrong with either.
