And as for the seperate beds I'd just simply get seperate mattresses or like the sleep number if you don't like the same stiffness and have separate sheets so there's no tugging and yanking. Keep the door hinge lubed and some old junk knobs make a clacking noise when you slowly turn themcto open and close so just junk it and replace it with a really nice high quality lever knob which doesn't make any noise inside. Put thin pieces of stick on foam on where the door touches the frame and using a flashlight inside the room while being outside the room in darkness helps you see the hot spots of where it touches. Nothing worse than a loud knob, hinge, and wood on wood hitting. Nothing worse than having different backs and the same bed to compromise, nothing worse than yanking sheets.
