The Hipark is one of the quietest hotels we've stayed in; inside the bedroom particularly, though in the living room (with the sofa bed) it was not bad, there's a door separating the main room door from the living room, it helps. Note however that there is a big building site next to the hotel, if your room is facing that side you could be woken up early in the morning by the noise. I would ask in the reception that they give you a room that doesn't face it...
Another very quiet and absolutely gorgeous hotel is the Marriott, still cheaper than a Disney hotel but not the cheapest around...
