We just got back from AoA LK room. I put in no room requests, and got a first floor room, 6508. It was great because we could walk in the entrance closest to the food court/buses and it was just a half hallway walk down to our room.
One caution, the walls are thin, so I'd try to avoid anything that could be considered a thoroughfare. It didn't bother us at night as we were heavy sleepers, I guess, but at midday break there were some pretty noisy people in the hallways.
