We have stayed at both and prefer the Polynesian over the BC. We felt the rooms were small at the BC, even though it is one buildiing it is very large and our room was quite a hike from an elavator, the cm's weren't helpful at all(I know this just depends on the cm and can happen anywhere). The pool was very nice at the BC and my kids enjoyed it but they also felt the pool at the Polynesian was very good too. The Polynesian rroms are very spacious, the convenience of the monorail and the ttc right next door is great, the grounds are beautiful and relaxing, great restaraunts and a wonderful family atmosphere. My kids are 18, 10, and 4 and they all prefer the Polynesian.
