For those of you who have fond memories of the Song of Flower, the Seabourn Pride might be a perfect fit. The suites are much larger although the size was never an issue for us on the Song. It might not be accurate, but the ship appears to be a bit larger and more spacious. The service, food and atmosphere are exactly like the Song and small group tours appear to be the norm.
I am posting on CC but would be happy to answer any questions on this board. We are having an amazing time.
