They're pretty much the same when it comes to rooms, but BCVs are in a separate building, a short walk from the BC. BC does have a spectacular pool if you want slides, whirlpools, lazy river, etc. If you just want to swim, the BW has nice pools, with one just for the villas. We really like the Marketplace inside the BC, which offers gelati, sandwiches, and other snacks, as well as a store. I love the Breezeway at the BC, which has a/c and comfy furniture where you can relax, have a snack, read, talk, whatever. The BW has a comfortable bar with 40's music & games. They're both wonderful.
