Hi Opera Girl,
we doing the Transatlantic cruise in november on the Splendour starting in Barcelona.
Weather might be very different, from warm weather to very stormy and really cold weather.
I opt for, as we call it in germany the onion-principle. that means different clothes one upon the other, so that I can took of clothes inside are when its getting warmer.
But I also take some gloves, hat and a warm jacket with me.
Somebody already asked this question on the german board and they all give similar answers.
Hope, it helps and its getting not too cold and stormy for both of us.
Best regards, Marita
