The whole thing is a bad idea. The policy should stay the same - you get what you get. I trust Couples to assign us a room in the category we booked. There may be a room we would prefer over another one, but we don't feel the need to control every aspect of our vacation so much so that we would be willing pay for a room to stay empty when someone else could be enjoying it and paying full price for it. It seems likely that Couples would lose some money on this, and I'd hate to have to pay more because some people can't go with the flow. Plus, shouldn't each vacation be unique? We loved the room we had last time, and we love to get it again next time, but a different room will guarantee a different - and maybe even better - experience. Please don't change your policy, but if you must experiment - try it at CSA.
