A few weeks ago we discussed the issue of trying to figure out the room layouts. I finally found all my Rhine/Moselle cruise photos and sure enough had take one of the detailed floor plan for the Inspire. It assume it would be the same for the other similar ships - Savor, Joy and Grace . Unfortunately it was in a binder with a clear cover so it isn't the best picture. Hopefully it's readable here or you can download and blow it up.
