We are trying to look for a place to stay in Paris that is close to a train stop. If we arrive at CDG if we take a train to Gare d Nord what other stops will the train make in the city or do we have to change trains at the Gare d Nord station? If there is another train from CDG that would make stops in Paris what is that train called? Could you please list the stops that a train would make from CDG to Paris that we would not have to change trains to get to once we leave CDG? Thank you!!!
