I'm guessing that the best view is from the dining room and living room, but still, when people come in the front door they see a long hallway that goes...to a blank wall. Perhaps you could skootch the bedroom suite to the right, swap the den and laundry, and have the door to the den at the end of the hall, with a window opposite the door? Or, instead of moving rooms, add a great archway or something just before the mudroom door, to have something to look at but really to mark the start of the back of the house, telling guests "nothing to see here, folks, turn and look at the great view."
