I have stayed both, I have stayed now at all deluxe. Poly comes in second, and BWI comes in third, everyone asks me why, and the only reason I have is, they upgraded us at BWI so I can't compare evenly when you pay for standard and get a 1 bedroom I really can not put that in the same category as Poly. We own DVC at Poly, I will probably never do a whole stay there, we love love love WL, we are doing 16 days there in May.
But for you, with your husband. I would either do a split stay and do both, or I would do BWI. I have to mention this, because so many people are telling you to check it out, there is only one resort in Disney I will never step foot in again, that is BC. It was and always will be the worst experience we ever had. It is filthy, inside just filthy, all hallways. So I would not recommend this resort to anyone. Definately not worth the price, I would go to pop or ALMs before I would go to BC.
