I voted for BC. I love the EP resort area. It is so great to walk to the International gateway. It feels very exclusive. It is so nice to leave after Illuminations and be able to wander leisurely home. I've stayed at the GF, not Poly, but really missed the convenience of getting out of the parks easy... MK is a great park to be close to, but there is no way to walk home unless you are at the Cont. Resort. The GF and Poly are so close but so far!!! You have to brave the crowds waiting for the resort monorail or boat launches to get back to your room. If you don't have kids, you can even walk back to the BC from Disney Studios! It is about a half mile and another exclusive, romantic walk. (Can you tell I love to walk to and from the parks?!) Have fun. I have not ever stayed at the Poly, but have been there many times for dinner and shows. It has always seemed like a hectic place, and rather more like a moderate hotel to me. But there are a host of dedicated and loyal Poly fans. Enjoy whatever you choose!
