We have consulted with Jill Cruise and a friend of ours who travels regularly to France. They both advised us that train trip from Paris to Marseille is three or four hours. Our friend tells us that it's not a difficult train ride. That's what we will be doing. we will fly to Paris and come home from Paris after we spend a few days before & after the cruise. We're waiting for Olivia to post the pre- & post packages.
Best wishes and we look forward to meeting you.
