In late April, we plan to take the train from Brussels Central Stn to Antwerp for a day trip one day. Then on another day, we need to get to Bruges where we will stay for a couple of nights before taking the train back to Brussels- (Midi/Zuid) from which we have pre-booked a Eurostar to London.
We are seniors 66/70 so understand we can get discounted return ticket as long as traveling after 9am weekdays. . For the day trip to Antwerp and getting to Bruges- can we just buy the tickets at the train station on the day of travel or do we need to buy in advance?
