Arriving Brussels Midi on Eurostar from London. I have one hour until my next train which is an Intercity to Luxembourg (no reservation needed). It doesn't seem like I save any money buying the ticket in advance. (I'll buy the Eurostar in advance as that will save money...I'm just referring to the second half of the journey.)
Question...should I buy the ticket from Brussels to Luxembourg prior to my arrival in Belgium, or will I have enough time after arrival to buy the ticket. (Travel will be early afternoon.) I've never had to transfer after taking Eurostar prior to this nor am I familiar with Brussels Midi.
