The Epcot resorts are our favorite!!! I would definitely give it a shot. I like that you can walk from BC/YC/Boardwalk for so many different food options, Boardwalk shopping and games, walk to Epcot, boat to HS.
We liked GF, but LOVED BC/YC/Boardwalk. We're giving Poly a try next trip, but still splitting our stay at BC since it was just redone. However, I tend to favor YC.
If you're worried about buses maybe consider staying at YC, since it's the first stop. I had a mixed experience with the buses at BC , but it didn't take away from anything. And then this past stay at YC I found the buses wonderful. During JAN one year when we stayed at BC the buses were HORRIBLE - they stopped everywhere. BC/YC/Swan/Dolphin and even BW. This was in 2010 and during a dead time, so they shared like crazy and they were crowded. I don't think we ever sat. This trip (earlier this month) we stayed at YC and the buses weren't nearly as bad AT ALL. Now I think it's BC/YC that share and then Boardwalk/Swan/Dolphin. We always got a seat and they were fast.
We split our stay this time with AKL, just because we wanted to give it a try. The theme was AMAZING, however, the buses killed us. They were slow, took forever, and we always stood because there was always a line and everyone wanted to cram on (I don't blame them - we waited forever).
We decided from here on out will be splitting our stay between Epcot resorts and MK resorts. We would stay at AKL again, but ONLY in a savannah room - that's the pull there and yes, it is worth it to see, but the length of time on a bus when we're used to walking or taking the monorail just can't be beat.
