MUNICH TO AMSTERDAM

There is an overnight train from Munich to Amsterdam. You can book it on www.citynightline.ch. With a savings fare, a bed in a private compartment is €99. Not only do you get your transportation, but you save the cost of a night in a hotel room and get another day of sightseeing.

There is a direct night train (CNL) that departs Munich at 22:40 and arrives Amsterdam at 08:56. You do not have to change trains on that one.

Thanks for the info guys. I rather take the night train as well but I could not find anything near 99 euro for September the closest is 198 euro per trip. Am I doing something wrong when I book?

You can book roundtrips on Lufthansa for €99 on their website. If you only need a one-way, book the return flight but simply don't use it. Alternatively, book AirBerlin, Germanwings or TUIfly to Düsseldorf or Cologne (one-way from €19.99 inkl. Taxes) and take a train from there. It's a very long journey from MUC to AMS otherwise...

To book a ticket on the night train, go to http://buchung.nachtzugreise.de (omit the "www"). Click on the British flag to view the site in English. SparNight fares, if available, will be shown along with the standard fares. Print your own ticket.

How many beds are you trying to book? It's €99 per person. All the fares I see on CNL's website end in 9; nothing with 8.

I checked numerous dates in September and found plenty of fares at €99 and even €79. Even on nights they were sold out, the standard fare for A bed in a double is €139.

Which website are you using?

My bad people I used http://buchung.nachtzugreise.de that you told me and i got the 99 euro fare. Thanks again for your help

could you please define 'spar night'?

"Spar Night" are discount fares for certain night trains offred by DB (German national rail). You can book either at www.bahn.de or http://buchung.nachtzugreise.de.

Sparen (pronounce Shpar' en) is the German verb for "to save". German Rail has Spar Preis (Savings price) fares for round trips. Spar Night is a low fare for night trains (only one way required).
