AoA with that crowd. I think 2 bathrooms and 2 sleeping areas totally wins. I also think they are young enough to appreciate the theming at AoA over Poly. To me, none of the amenities of a deluxe can outweigh the three beds, 2 full bath, better refrigerator, size, for that group.
Can you have a noisy neighbor? Sure. But my second worst sleeping night was at AKL due to an obnoxious neighbor. So - the quiet level is unpredictable.
