You could even use these 8 carriages for Tues/Weds nights after the match
It runs ecs back from Littlehampton to Lovers Walk. Maybe run to HH after Preston Park, then to Lewes (Newhaven if you must). Gets another 8 car thru Falmer.
České Budějovice
Is only a couple of hours on train from Prague. Got a massive square with bars & restaurants all around it. Stayed there a few times. Great place!
