France
When in Prague be careful to double check the name of the station your train is leaving from, as Hlavní nádraží and Holešovice Nádraží can easily be confused if you don't. This can result in you missing the train to Berlin and being over 8 hours late to meet the people who have flown out from england for 2 days just to meet you there, which can lead to lots of arguments.
When travelling to the South and East of France by train some destinations are best reached via Lille rather than Paris - you do not need to change stations and journey times can be quicker.
