Considering adding a few days pre-cruise to go to DLP and Paris. I am wondering what the best way to do it. Train or Fly from Paris to Barcelona and where to stay at DLP or in Paris? Is the train safe and what stations to use and where in Barcelona in regards to port will the station be? Would it be okay to take the overnight train and get in the morning of the cruise. Also if anyone knows of any tours to do in Paris?
