Planning a trip to France to see Paris, Normandy, and Brittany. Plan is to take a train from Paris to Caen, pick up a rental car in Caen, return rental car in Rennes, and take the train to CDG. We're looking for suggestions on what is a must-see in Rennes, as well as restaurant and hotel recommendations.
Since "must-see" places vary depending on each person's interests, you can find yours on the official Rennes tourism website.
