I want to go from Gorinchem to Amsterdam. I have NS Flex Dal vrij. I check in in Gorinchem in daluur, take Qbuzz train to Geldermalsen, there I overstep to NS train during spitsuur, and then I checked out in Amsterdam.
Question: will this trip be free for me? Because I started the trip in daluur and I have NS Flex Dal vrij. Or I will pay the full price, because I change from Qbuzz train to NS train during spitsuur?
