I'm planning on getting a train out toward near Eastbourne after the match on Saturday. I've got a couple of hours to get there (ideally arriving no later than 7). How long does it normally take for that side of the train station to clear up? I'm trying to decide if it's worth lingering at the amex for a little while then strolling straight onto the platform, or if there will still be queues, and I might as well just join the queues right after the match?
