On Cunard, the transatlantcs are CROSSINGS, not cruises. Cunard regulars will be sure to point this out to you onboard. So just giving you a heads up
Take your best clothes. Cunard is much more formal than most cruise lines. QE2 is even more formal than QM2. But either way, you won't see a lot of Levis or sloppy shorts/tank top outfits. And EVERYONE dresses for dinner. Formal night is truly a splendid event-90% men in tuxes and ladies in long, beaded gowns.
I will be on the QE2 again for another January crossing. Hopefully, we'll get to rock and roll across the Atlantic. Captain Rynd last year took the out of the way southern route and we missed all the weather. This year, we have Captain McNaught. He won't wimp out.
Enjoy the blessed sea days. Sheer heaven sitting on deck watching the world go by.
