I think I am in the minority here, but I prefer BWV over BCV right now for a variety of reasons. My kiddos are now 8 and 6, and we haven't been to BC since they were 4 and 2. Of course, now they are much stronger swimmers and older than they were then, but the sprawling nature of the pool is a turn off for me. At BWV, the pool is spread out enough where my kids feel like they have some independence but small enough that I can have eyes on them constantly. The slide at BWV is one of the better on property I think. We also prefer the BWV theming over the BCV theming, though the room layout is the same I believe in each, other than the 2BDs of course as BWV only has the 2BD lock-offs while BCV has the dedicated 2BDs.
I can't remember if your family has stayed at BWV before, but that is our favorite of the two in the Crescent Lake area! We will definitely stay at BCV (if we can get into a 1BD at the 7 month mark!) in the future once my kids are a bit older and more independent so as to enjoy SAB with a little more peace of mind than we'd have now.
