Head back into Avignon after lunch to check out some of the other attractions that will interest you.
The Musee Angladon (open Tue-Sun 1pm-6pm) is an enchanting museum that contains the magnificent art collection of Jacques Doucet, renowned Parisian haute couture designer. Doucet cultivated a number of young artists, among them Van Gogh, Picasso, Braque, Max Jacob, Marcel Duchamp, and Guillaume Apollinaire, and began to collect their early works.
If you're still in the mood for more art, then head to Musee Calvet, an 18th-century mansion that features the works of Vernet, David, Corot, Manet, and Soutine, plus a collection of ancient silverware.
Head back to the B&B early so you can spend an evening sipping on the wonderful wine you purchased, while the kids can run around the grounds.
