I’m looking to travel from Berwick upon Tweed to Edinburgh on Sunday next week and return the same day. It’s for a theatre performance, so the return time isn’t exactly known. I was under the impression that LNER had these new fangled Advances that allowed a certain amount of flexibility for a slightly higher price. However I can’t seem to see these on the LNER booking site. Failing that, is there a different destination I can book to to get an off peak return, that allows me to exit/entry at Edinburgh Waverley?
