If you need to cross in Winter usually only ship going is Cunard. Considered a liner, its abit different from our more Americanized lines with empathisis on the ship being the vacation. If you are younger do consider NCL with its small single cabins, no cabinmate needed. But they start probably in April.Go to your public library for cruise books.Most of authors have web sites too. Cruisecritic. com for reader reviews.Look up itins and sample discount pricing on Vacationstogo.com. Excellent bargains, especially this year, several months in advance. Have done 2 NCL Transatlantics and was treated beautifully by staff.
