Paul, if there are only two of you what would you do with the 'extra' space? There's a bed made up permanently, which if either of you want to nap, is ready and waiting, there are still two sofas, one each, for lounging on during the day - there's still a kitchen, wardrobe, vanity unit, shower cubicle and so on. Apart from that you don't spend the late evening wrestling with cushions, making up beds (unless you're the kind of caravanner who prefers separate beds and makes do with a sleeping bag on the sofas)or the early morning packing them up before you can sit down for breakfast. We prefer a nice comfortable bed, made up for when you want to fall in it, and not one that has to be packed away each morning and unpacked again at night.
