In regards to the configuration of the room, if you book a room that will hold 3/4 guests, the head of the bed will be under the window. I’m fact, on most older ships, the bed is always under the window. If the cabin only holds two, the beds are often on the side wall, so you can stand by the window. And the windowsill is deep, so you can store things on it. But the windows are most often too high to offer a good view if you are sitting in a chair ( unless you are really tall). An exception is some newer cabins on deck 3 on the M class ships. They were created from conference rooms, and have extra large round windows. These are cabins aft of the atrium. Not all cabins with round windows are portholes. EM
