BCV has Storm Along Bay. I like the table set up in the dining room better. There are dedicateds, (some with two queen beds, some with a bed and a pullout) and lockoffs. The BC atmosphere is a little quieter.
BWVs has bigger closets. All two bedrooms are lockoffs. You have three choices of view. The BW atmosphere is a little busier.
Personally, I think they are fairly interchangable. They are close enough that the restaurants, transportation and location are pretty much the same. The bookable views at BWVs are nice, as are the dedicateds at BCVs (though both need to be booked early to get the in demand types), leaving SAB as the real factor. Most people really like SAB, some people don't or it really doesn't factor.
