Yup, the train is the best, and usually the fastest, too. But when you've got a couple of weeks' worth of luggage and a load of demo equipment with you... It's not ideal. The luggage space isn't fantastic, particularly if you arrive during rush hour.

Don't forget the Zuidtangent if you're headed to De Hoek or Hoofddorp as well... Or Schiphol Sternet for Schiphol Rijk, Aalsmeer, Amstelveen, etc.
