Hi Tom, I used to ship out of Plymouth to Santander with furniture down to southern Spain . I liked Britany Ferries there were always clean cabins and good food. The only thing was as you round France into the Bay of Biscay you catch the Atlantic on the side giving you a roll. Always had Sturgeon sea sickness tablets in my pocket so no problem, used to watch the dolphins jumping the boats wake in the late summer ,lovely spectacle.
