Just looking at the options for travel for a group of my partner's friends to travel to watch tennis in June all hold Senior railcards. Current plan is to travel at 0952 Southern service and change at Clapham Junction with an off peak return via Kensington Olympia @ £24.05 On the return depending on the time they may prefer to travel via Victoria & Euston presumably their tickets could be excessed to via London Terminals, would this need to be excessed before leaving Eastbourne or could it be done on the train?
