You ARE doing the right thing, my wife is half way through a 24 mth chemo treatment. She has to go back to Sheffield every 3 wks for 4 to 5 days, she uses the train so we have been cruising between railway stations, its not that bad. Since May we have been to Banbury, Warwick, Alvechurch, Stratford, Leamington Spa and now I am near Sutton Stop so I can meet her in Coventry tomorrow.
Advance booking on line, on average she pays about £10 single, for some reason 2 singles work out cheaper than a return, much better than staying at home.
