I had a Brighton - Haywards Heath Off Peak Day Return today. I used the outward part but on the way back I wanted to go to Hove. I know the fare from both stations is the same. I asked the booking office lady if she would do an excess fare and with a smile and matter of 20 seconds did me a zero rated excess to Hove. But afterwards I thought, you could actually get a Haywards Heath to Hove and change there for Brighton. Not sure if its a permitted route, hence covering myself in case by trying to get the excess. Did I therefore need the excess or could I have exited at Hove on a break of journey/stop short?
