City Night Line is having a two-for-one sale on their overnight train rides (http://www.citynightline.de/nachtzugreise/view/en/angebote/buy1-get1free.shtml). The site says: "The offer is not available online, but at most European train-ticket outlets." Just to be safe, I'd like to book tickets before starting the trip. Does anyone know if there would be a way to reserve the tickets before then, perhaps through a European travel agent?
Thanks.
