Looking for the best way to get to Brussels direct
There are many direct trains. You can board either at Amsterdam Centraal or Amsterdam Airport. Thalys takes about 1 hour 34 minutes from Amsterdam Airport to Bruxelles-Midi. You can check the schedule etc. on Deutsche Bahn website.
The standard 2nd class fare on a Thalys train is €84. To get a discount fare as low as €29, book ASAP (up to 90 days allowed) on thalys.com. Discount fare tickets are for a specific departure date and time and are non-exchangeable and non-returnable. Be sure you can commit before booking.
With the Fyra train uncertainties the best option is a Thalys train.
Thank you to all.
