Two weeks in Provence Fall 2016

I've done a lot of what you intend, and your plan seems very thoughtful and well paced.
I love Montpellier, and although it's not Provence, I would suggest it as an option after Pont du Gard.

This sounds great - I think you've got it covered. Three things that we enjoyed in Provence that I want to call out are the Carrières de Lumières and the little towns of Suzette (Cote de Rhone wine road in RS Provence book) and Joucas (Luberon in RS Provence book). The towns are very charming and the wine that we bought from the the winery in Suzette was very good (I'm not an expert so take that with a grain of salt). The Carrières de Lumières is like nothing I've ever seen before or since.

I really enjoyed Stes-Maries-De-La-Mer. I'm not sure how bananas it will be during the festival but I would lean towards giving it a try. The town has a lot of parking for folks going to the beach, so it might not be as much of a hassle as it seems. That said, I've not been to the festival, so I'm just speculating.

One more thing in regards to Uzes - there was an older post on this board asking for advice on how to spend time in that general area - I thought the responses were helpful so I've included it below:

Orange has just one main attraction; the Roman theater. I suggest you look at Fontaine-de-Vaucluse, Rousillon, and Carpentras as alternatives or to fill out your day, once you've seen the theater.

We drove around Provence for two weeks last summer and saw most of the places on your list and I think you have made a pretty good plan, so i will only make small suggestions.
A place that I find very fascinating and very underrated is the ruins of a roman aquaduct and watermill complex at Barbegal, just outside Arlas on the way to Les Baux. https://en.wikipedia.org/wiki/Barbegal_aqueduct_and_mill
Granted it's not as impressive as Pont du Gard, wich is hard to beat and i am a huge buff when it comes to aquaducts and waterpower, so i might be biased. But it is a lovely aquaduct going trough an olive grove and it's completely devoid of tourists.

In the Luberon Gordes and Roussilon are the main draws and they are very nice, but also crowded with tourists. We found the town of Saignon to be just as lovely, but with a fraction of the tourists.

I have also driven a number of times to the areas you are going to visit and it would not be too much for me, but you can always change your day trips at the last minute if you find something more interesting. When you say you like staying in smaller towns or B&Bs in the countryside I am not seeing much of that. Arles is a relatively busy place and I found driving in and out to be a little problematic. I always stay in St. Remy as it is central to many wonderful places as well as the small town ambience that I prefer, and a wonderful market.

I have flown out of Marsailles and to avoid any problems I have stayed there the night before. One time we went to return rental car early and the office was not open and it was difficult to tell what to do. It worked out ok, but I don't mind a nice dinner in Marsailles and not have to worry about any issues for the early plane.

I love the Carmague and have visited a few times. It is definitely a totally different experience, but I loved it and a few times there were tons of pink flamingos. The beach town is charming but have not been there during an event. The Abbey de Senague (sp) near Gordes was beautiful... there is an unlimited number of wonderful experiences (some of the best are just wandering around markets, villages without a plan:)

Thanks for the suggestions to all.

I just wanted to say that we were driving that area in early Oct. We stayed in Roussillon one night, very pretty sunset reflecting off the ocre buildings and Fontaine de Vaucluse I loved. Worth a trip from L'isle sur la Sorgue if you have time, imo. Loved the whole area, probably hard to go wrong anywhere. Pont du gard was amazing even in the pouring rain and the Camargue(we stayed in St Maries de la Mer). I went horseback riding our second day there, made my trip:)
We also drove along the coast between Nice and St Tropez before heading inland to Roussillon, Gordes, Bories Village(was so so), Senanque Abbey, Fontaine de Vaucluse, Avignon(just to go to the Popes palace), Pont du Gard, Arles, Camargue....I pretty much enjoyed it all:)

Gigondas is a winner, but so is Chateauneuf du Pape. We found Gigondas to be more manageable in size, with VASTLY better parking, and more than a few little spots for lunch. Pierre Amadieu winery was a hit for sure.
