Paris, here we are!
Lesson learned: If you get into Charles de Gaulle airport after 11pm…be ready to take a taxi into city centre! The last train left at 10:55, and the buses stop around then too. It took us lots of walking around the airport to figure this out, especially getting different information from different people. Apparently there’s a night bus, but the guy at information didn’t seem to think it was that safe? Good to know for next time!
