I remember that Alan! When Mrs J to be was in Brighton and I was in Manchester there was a lot of weekend travelling (Sat night southbound, arriving 11pm or so, Sunday back similar timing
) The £10 upgrade made a lot of difference.
Sam, yes, I rate the Virgin experience on the Pendelinos as being about the best. I use 1st where possible because of the space, quietness, free drinks etc. the waiting Lounges at termini, the power sockets at the seats, the tables at every seat etc. I usually work on my journeys, and usually charge my business. Apart from that I can't/won't travel on a train standing up; 1st Class I get a much better probability of not having to wait for the next train.
