He wants to go from Marseille, France and travel to Italy. In Italy he would like to start with Genoa, Milan, Venice and end in Florence. We thought it would be best to travel by train so that he can stop as he wished to take in the scenery. How easy is it to get a train from Marseille to Genoa?

It's easy. Just buy a ticket and board the train. Check your schedule on Deutsche Bahn website. On this page click on Favorite Links and that takes you to DB website. From Marseille to Genova you will have to change trains at least twice. The fastest connection takes little over 6 hours.
