My family and I will be stopping in Brussels for a few hours on our way to Amsterdam next week. It is my understanding that our Thalys ticket from Paris to Brussels is good for continuing to Brussels by local train from Midi to Centraal, and I just have a few questions about the process.
1. Does it matter where we sit on the local train to Centraal? Is there assigned seating like on Thalys?
2. On the return trip from Centraal to Midi, can we just show them our Thalys ticket from Midi to Amsterdam and they'll let us board?
