After arriving at gare du nord, we plan on going from there to the eiffel tower, from the Eiffel Tower to the Louvre, then from the Louvre back to Gare du Nord. I heard the Metro is cheap and easy, but the less line changes, the better. I read that there’s a 9 € one-day travel pass, is that for the Metro or RER? Which do I ask for to get me there and back? Will they speak any English at the station and where do we go? I’m a nervous wreck…I’ve been to Charles de Gaulle airport, but this seems much scarier!
