Portholes versus windows

Like all who have been through the sanatorium regime I can't sleep with my window closed. Well, as you can guess this is something of a problem on a ship. No way could I have a cabin with a tiny porthole. So Malcolm ( bless him) agreed to upgrade so that I would have a window. Except it doesn't open. That would have cost an eye-watering amount more. So I am content with at least a proper view outside.
