That sounds great. I’d go to Avignon and wander in the Place l’Horlage and also go to the Ferris wheel. There are these little site seeing “trains” (think mall train) you go to the major sites in. So many nice towns to take day trips to or to stay in. I loved Gordes. We also went kayaking near the Pont du Gard and there were children doing it. It is a calm water trail.
Wherever I go, I try to see towns on their market days. I found this listing of market days in towns near Avignon.
