I recently travelled from Dusseldorf to Amsterdam and got a group ticket. Was £16 each for 8 of us (I think you buy it in 5's). Should work the other way around - but you shouldn't have to pay £50, just go to the desk.
Group travel in Germany is where it's at, saved hundreds of euros over the years. "Schone-tag ticket".
Cheers.
I will look into it nearer the time, just wish our trains in the UK were similar prices! Struggle to get to bloody York for £20 and that's only down the road.
Tell me about it. I got from Dusseldorf->Amsterdam (3 trains) for the same price as it took me to get to work (Glasgow->Edinburgh) each day. Was so bad I ended up moving so now they get nothing, the bastards.
