Transatlantic late Oct Spain to Fla.

We have done several transatlantics, mostly westbound, and never had rough seas. And, I am susceptible to seasickness. The only time we experienced really rough seas was on an eastbound spring trip in the North Atlantic. That trip originated in New Jersey, and we could not go outside, even topside, (and shows were cancelled for safety of performers) for three or four days. I even developed sea legs by the fourth day. It was so bad, Celebrity, as I recall, cancelled all future transatlantics in the North Atlantic.
