I've stayed at all of them other than WL and Saratoga Springs, it's really according to what your goals are. Do you enjoy Epcot? If so, either BW or YC are great, just a hop skip and jump away. I prefer YC over BW but that's just personal. If you don't plan on spending a lot of time in the parks and want to do a lot of exploring and hanging around the resort, AKL is great. If you want understated elegance, you can't beat the GF, it's beautiful. The Poly and BC seem more kid friendly to me, I like them both but they do seem to have more kids running around. OKW is o.k. if you want the laid back home feeling type resort, it's the oldest DVC resort and is showing it's age a little, but the rooms are huge, the grounds pretty and very relaxing, it would be my last pick but just because I'm not fond of buses.
