After an extensive conversation with three Thalys customer service representatives via their Facebook page, I have learned that they do not have anything in writing on their website which states that my ticket from Amsterdam Central to Brussels Central will actually get me all the way to Brussels Central.
Here is what I bought: three tickets from Amsterdam Central to Brussels Central on August 9. The confirmation e-mail and the tickets state that the tickets go to Brussels Midi Station. The only place that says that I will actually get all the way to Central Station is when I click the tiny “i” icon on the booking confirmation page of their website, which opens a pop-up window which states:
“Bruxelles-Midi/Brussel-Zuid - Brussel-Centraal/Bruxelles-Central
The route above is a part of the same zone and is included in the price mentioned. You therefore do not need to buy a separate ticket for this route.”
But I don’t think that will help me very much when I try to board a train from Midi to Central Station. Don’t you think it’s really odd that a ticket from Amsterdam to Brussels Central says nothing about Brussels Central? According to Ann, Valia, and Patrice from Thalys, I shouldn’t worry about it and it’s no big deal. Yet they were unable to show me anything that said that I would be able to board a train from Midi to Central.
