We need help planning an itinerary. We would either fly into Nice, CDG or MRS and take trains and buses from there. looking for suggestions on places to visit without a car that capture the true essence of Provence, from large towns to smaller ones. Proposed itineraries welcome. We have been to Avignon, Arles and Orange before, so we don't feel the need to visit these towns. If we could base ourselves in one or two places only and day trip from these that would be great, but open to other ideas.
