You can book a group of up to 9 passengers on NSInternational.com, at a NS International Service desk, with NS International Customer Service on 030-2300023 or your NS International Travel Agent.
If you are unable to book 9 passengers at once for your destination, you can make multiple bookings. In that case, however, in cannot be guaranteed that you are booked in the same coach. The train of your choice is probably already very full and there is no room for the whole group in the same coach.

What next
