On my last day of travel in Belgium, I will be leaving Bruges for Rotterdam. I may or may not be making a stop in the town of Kalmthout to visit the Kalmthout Arboretum. Either way, this will be my 10th and final trip using the ticket.
Would I be able to use my tenth journey ticket to travel to the city of Roosendaal, Netherlands (using a standard Roosendaal ticket) from either Bruges or Kalmthout and then purchase a Netherlands Rail ticket for the remaining portion of my trip to Rotterdam from Roosendaal? In the terms of use for the 10-journey ticket it says that the ticket is good for journeys between two Belgian stations/stops, not including border stations. If I will be unable to use my tenth trip for the journey to Roosendaal, can I use the closest town to the border (Essen) as my destination and then buy another ticket for the trip from Essen to Rotterdam?
And finally, is there a ticket counter at the Brussels National Airport where I can purchase the 10-journey ticket?
