As one who has visited Japan many times, I think of a ryokan as take it or leave it. I did a few ryokan nights years ago and was a bit underwhelmed. Since then, I just don't bother. I prefer sitting on real chairs, sleeping on real, western-style beds, coming and going as I please and ordering my meals as I feel at the time. Now, as I've gotten older, even just the thought of doing anything on or near the floor makes my back and knees hurt. YMMV.
