That's quite a tour, 1100 Kilometers in total.
From Hamburg just follow the motorway A1 southwards via Bremen, Münster, Dortmund (Ruhrgebiet), Wuppertal to Köln (Cologne). Then change onto the A4 westwards to Aachen (wave as you pass). Just before Aachen you have to change onto the A44 into the direction of Belgium (next city is Lüttich (or Liege in French)). Then when you passed Lüttich you have to change onto the A15/E42 (the Lüttich airport is on your right). Then comes Namur, Mons and Valenciennes (border to France). In France you will be on the N30 which becomes the A1 (toll motorway). Your main destination is Paris now, rough direction Nantes/Orleans. Take care that you manage to take the exit to the A10/A11 to Chartres, follow the A11 to Nantes. At LM take the LM south exit. Have a good drive, it's quite a bit of miles.
