I am travelling from Brussels airport (Zaventem) to Bruges on 24th of December and back from Bruges to Brussels on 25th of December.
Should I buy tickets in advance? I am not really concerned about the price (unless it is twice cheaper or around that), but about the place availability.
Additionally, this post suggest that one should not take high speed trains but rather regular SNCB trains. Does the price for these "regular SNCB trains" differ that much from the "high speed trains"?
