We are travelling from Brugge to Diekirch, Luxembourg on September 16. I checked DB Bahn and found almost hourly connections. However, these tickets cannot be purchased online. (Our preferred route is Brugge>Liege>Ettelbruck>Diekirch -- one intercity, one interregio, one regionalbahn).
Is it worth the effort to call and purchase these tickets now, or would the price be pretty much the same if I purchased them when we arrive??
