We had an aft mini on Dawn (536 sq feet) and we had an additional adult with us. The reduced rate is for anyone. In our case, there was a separate hallway to the dual bathroom. You had a toilet and sink in one room and a doorway through to a sink and jacuuzi tub. We also had a full curtain that could be drawn between us. Since the additional adult was my sister-in-law, it was more tolerable - and it was the only way we could affort it. We split the entire cost three ways. The hide-a-bed couch was smaller than a double bed, so I don't think two adults would be very comfortable. Also, the mattress on it was awful (more like an exercise pad). As soon as my sis saw it, she insisted on a real mattress. Our room stewardess suggested she wait until the following evening, but was very accommodating and came up with it while we were out for the evening show.
