Will be 7 days in Paris prior to Normandy cruise. Suggestions as to villages/towns around Paris of interest.
What interests you? Churches, markets, architecture, wine, art, chateaux? There are dozens of places to suggest but more info is needed.
Chartres is about an hour away, if you go on a Friday you can walk the labyrinth inside the basilica. Fast trains can get you to Reims in under an hour, Amiens in about an hour, Rouen in 1.5 hours. All great daytrips.
More info on what you like would be helpful.
