It really depends on when your cruise crosses and what route you are going to take. So...when and what are your ports of call in order? ....Neil Dow.
For westbound transAtlantics remember it is best to have the port-side balcony room to maximise sunligh.
Depends on the time of year. They usually start moving them to the Caribbean around October time. I have done this trip out to the Caribbean and you have to cross the Bay of Biscay which when we went (Oct) was very rough, a lot of people got sick, I am lucky I dont suffer sea sickness, but its something to have in mind. We fly out now instead.
