Without looking to discourage anyone from contacting me to accompany them on a daytrip to Normandy, I recommend that travelers wishing to see highlights alone and simply in need of transportation seek out one of the daily touring companies specialized in group D-Day tours and setting out from Paris, Caen or Bayeux.
For my private daytrips from Paris, including transportation, count 1300-1425€ for 2 plus 100€ per additional traveler. Cost varies depending on specific destinations within the D-Day Landing Zone.
Having said that, my clients have sometimes already planned to rent a car on their own for more extensive travels outside of Paris and then ask me to accompany them for one or two days in Normandy without my having to arrange or factor in transportation costs. In the case, my fee is 650€ for 2 plus 30€ per additional traveler, plus hotel costs if overnight or longer.
I’m actually a fan of 2-day/1-night excursions and 3-day/2-night Normandy tours, whether organized and guided throughout by me or not. So inquire about those if interested in a more relaxed and extensive excursion to Normandy.
Also inquire about multi-region trips that include Normandy: the WWII war sights of Normandy and the WWI sights of northern France or the D-Day Zone of Normandy and castles of the Loire Valley Because of the variety of sights, tastes and encounters, multi-region tours can be especially interesting for families with teenage children and for 4 or more adults traveling together.
