Hi, my wife and I would like to take a side trip to Cologne while visiting Amsterdam in 2 weeks. If I purchase tickets at http://www.ns.nl , I get almost a 50% discount because it's going to be a round-trip (superreturn tickets) and the two of us will be traveling together. However the tickets will have to be sent to an address in the Netherlands. Does anyone know if I get the same kind of discount if I purchase the tickets at the train station when I get to Amsterdam in two weeks? If not, is there any VT member in Amsterdam who is willing to help me out by letting me use his/her address for ticket delivery? I can pick them up once I get to Amsterdam. I can be reached at email@example.com. Thanks a lot.
