I want to get the 6.00 train from Portsmouth Harbour to Exeter returning at 12.26 the same day. Both Eastcoast and First Great Western websites are showing that neither an Anytime Day Return or an Anytime Return is available for this journey and that I have to buy two singles. I don't understand - surely if I have an Anytime ticket - valid on the 6.00 - I can use it to come back on any train? Or have I missed something?
