Utee spent a lot of time in France, so he knows it better than most. Nince days is tough though, the first day for me is jet lag city. I THINK Paris has to be the focal point for a new person going to Europe, if that is the case. Here is my itinerary, geared more for me:
3 days in Paris
Drive to Bayeux for 2 nights.
Drive south to Mont St. Michel, stay one night in the town.
Now it's tough, maybe I'd make my way back up the Loire Valley, staying in Saumur maybe, seeing castles and wine places. Orlean?
Last night in Paris, probably at CDG.
The problem is missing Provence obviously. And Burgundy. And the Alps. And Bordeaux.
we did one driving trip from Paris going the other direction, including Strasbourg up into Luxembourg then Brussels, that worked too.
