I think it depends on what you're looking for.
We stayed at the Beach Club last August. I requested a room closest to Epcot, and that's what I got... a room pretty much right above the "back door." Of course, that meant we were pretty far from both SAB and the lobby, but it sure was nice late at night when we were all tired; we were just steps away from Epcot.
Next year, when we return, I'm thinking of leaving it in the hands of the booking gods and seeing what we get. I'll only request a full balcony; that's important to me.
But what's important to you? Quiet? Being close to SAB? Closer to DHS? Close to the lobby?
