Y&B / BWV
We just stayed at the BWV on our last trip. We toured it during the opening celebration in 1996 and had always concidered it, but for some reason or another, never actually stayed there until our last visit to the world.
We stayed in a two bedroom villa with a 'preferred view.' The view itself made the resort for us. It was absolutley amazing: 5th floor, over Big River and the DVC center. with great Epcot fireworks viewing. The interior was on-par with other DVC resorts. Be prepared though, we noticed that if you choose to bring a vehicle or rental car and self park often, it can be a long walk to your room if your room is on the very far end of the Boardwalk. As someone pointed out before, the good thing about the Epcot resorts is their proximity to both Epoct and MGM. In addition, the additional dining options at the Y&B are enjoyable. That being said, I'm a Beach Club kinda person, and from that perspective, the additional Boardwalk features are just steps away. Either way, I don't think you will be unhappy at either resort. Enjoy your trip!
