Train from Schiphol Airport to Den Haag Central (http://www.ns.nl) 

• Go to the main hall / train station (indicated with symbols)
• Buy your ticket at the ticket office in the main hall since the yellow ticket machines do not work with credit cards (one-way €7.00 2^nd class or €11.40 for 1^st class). The trip lasts about half an hour.
• Take the escalator down to platform 4 or 5.
• Take the train to ‘Den Haag Centraal’ at 4 or 34 minutes past the hour (direct train, platform 5).
• If you are more adventurous and can’t wait for the next: Take the train to ‘Leiden Centraal’ and switch to another train (on the other side of the platform where you get off in Leiden) with destination ‘Den Haag Centraal’. If in doubt, consult the train managers in blue uniforms. Timetables (big yellow boards) are at each station.

Local transport in Den Haag  (http://www.htm.nl)

• Easiest solution: take a taxi (about €15).
• Cheaper solution: take a tram. You might have to ask at the public transport desk in the main hall of the train station which one to take. You need a ticket (called ‘strippenkaart’). You can buy a single trip (2 zones) or a larger one if you plan on more sight-seeing. Buy it in the main hall.
• To the Dorint/ Bell Air/ Convention Centre:  From The Hague Central Station (CS) Take tram no. 17. You get off at the Statenplein stop.
