I'm not seeing the price you listed, where did you see it? Or are you getting a past cruiser or other discount? Best I see is $699 with $75 OBC each.
Have you done QM2 before? I want to go transatlantic and the dates are good but it's an old ship so I'm a bit hesitant. Stuck on a ship you don't like for a week with no ports wouldn't be fun. Unfortunately I'm missing the other transatlantic opportunities as I'll be on another cruise until the 25th of May.
