If you were visiting europe what would you see?

I would loose completely concentration camps from the route. Nothing to see there, this part of Poland is goats and sheeps only, and huge detour for it. You will learn way more by visiting NS museum in Cologne, El De Haus; is the former headquarters of the Gestapo: http://www.museenkoeln.de/ns-dokumentati...aspx?s=315

Will add Cologne (catedral, 36 museums and great town, Koblenz and Lahneck Castle, Prague, Budapest)

IMO if you have not visited Prague and Budapest you can't say you have got European trip.

And why anybody would want to see Andorra? Then you have 550 miles from Andorra through the most boring part of France to Paris? Except Milau viaduct nothing to see or do on your chosen route there.

This trip for 7 days is a complete waste of time. You need to plan less travel and more sightseeing. Otherwise you will see European motorways and roads only not the things that worths seeing, because you will travel most of the time. You need at least 3 days for Paris only.
