We've stayed at both and I liked BC better - it's a bit quieter, closer to Epcot and has a great feel. Our room at the BW was so far at the end of one hall we felt like we had a haul just to get to the elevator! If you stay at the Epcot end of the BC it takes only 5-10 minutes to walk to the park - which makes it that much easier to beat the crowds at night after Illuminations. Frankly, the pool area at BC cannot be beat, for both kids and adults. The BW pool doesn't compare. But if you stay at the BC just a short stroll takes you over to all the BW has to offer - restaurants, night life, etc. - giving you the best of both worlds!
