I've driven to all options on route Polegate, Lewes and Bridge car park and personally I find driving to Polegate the easier option for mid week games. The trains on a Saturday are very good. I normally get the 12.29 from Warrior Sq which is a slow train (1hr 5mins) but allows just the right...
Only thing that lets it down for me is the poor service back to Hastings for midweek games. Can't get back to St Leonards until 23.50 so end up having to drive. If I drive I still don't get home until approx 23.30, but it means my lad can attend midweek games.
