My husband and I are arriving in the south of France at the end of this week. After spending planned time in Languedoc and Provence, we are footloose in the Riviera for the last 4 days, but at a loss how to organize them. We're hoping to avoid the August crowds and stay in small villages and do day trips. Can anyone recommend a good central village or does it make sense to travel without reservations? In such a short time, what are the must-sees? The big crowded places we will bypass and see at another, less crowded time of year. All ideas gratefully received.
