The Queen Mary 2 has a virtual monopoly on trans-Atlantic service. Cunard is also probably the most traditional line today. This is why I chose the QM2.
Cabin was more than I had expected - far better than what I had experienced on the QE2 quite a few years ago.
Food ranged from average to very good, generally hovered around the average mark. Restaurant (Britannia) service was polite, often gracious but could be slow - probably due to understaffing.
Very comfortable and well equipped.
