Don:

I have done 3 transatlantic cruises. All of them were along the southern route. One on Seabourn Legend, two on the Royal Viking Sun (about the size of the Voyager).

My experiences may be unique, but the weather was ideal for both of the east to west voyages. One evening dinner was served on the pool deck (we were in the middle of the Atlantic). We used the pool every day and the cruise staff planned may activities including enrichment lectures on a variety of topics.

We did have some rough weather traveling west to east on the third crossing, but it was in early October and I think we encountered a tail end of a tropical disturbance. We still enjoyed the cruise but had 3 very rough, cloudy days.

I have heard many bad weather stories about northern crossing, but have no personal experience.

We have always enjoyed "crossings".
