We are planning a trip to France in June, 2010. We plan to rent a car in Avignon and spend 2 nights in Roussillon so we can explore Luberon. Any suggestions on an itinerary? We want to visit Gordes, Le Colorado Provencal, Saignon, Buoux, Lourmarin and Isle-sur-la-Sorgue but prefer a more relaxed pace. Any other "must sees" in the area"? We are also looking at purchasing a GPS (Garmin 1370T) for directions in France. Has anyone used it for driving in Provence? Thanks!
