Thank you Kokopelli. We now have an accessible cabin, so know the situation there. The cabin category that I bid on, has a couch, which I'd love, but will probably lose the accessible cabin, so would need the separate piece to put onto a regular toilet. I CAN step over into a regular shower, but need the bar/extra height of the other. Also, I tried dealing with the special needs dept when first booking, and found them very unresponsive...so hope to just get a photo from someone who has used one of the separate risers.
