Having travelled first and second class to and from London and Hannover, I can only say that I wouldn't consider doing it again in cattle.
I couldn't do the long and arduous trip without the complementaries, and the mutterings of fellow passengers complaining about the temperature of their (free) shampoo above the cries of our two year old ...
In fairness most of them loved our two year old. Didn't bump into ol' Nick, or any of his contemptoraries. Shame really.
