http://www.gner.co.uk/GNER to buy in advance and then you can pick your ticket up at the Edinburgh location when you are ready to go..but they said you need to enter a London post code to buy the ticket! I thought the trains would just come into a major station like Kings Cross or something. What postcode do I enter? Ultimately I will be staying in Paddington but I figured I would get a tube connection from Kings Cross or whereever the train stops.
Thanks in advance for your replies. :)
