My husband and I would be in France in October end, and this time, the base is going to be Lyon. (first Annecy, then to Lyon for 12 days). Having missed Aix-en-Provence last fall, when we traveled in Cote d'azur and Provence, i was very keen on going to Aix this time. So have booked our tickets on TGV (Reaching Aix TGV station at 8:06 AM. Departing at 17:29 PM same day).
My question is about our plan for the day. I would appreciate any input greatly.
 We will take the Navette from TGV station to Aix Center reaching Gare routiere on Av.de l'Europe.
 First, we would like to go for the antiques/flea market at Place Verdun (it is a Thursday, so I am presuming that the market will be on). We will walk from Gare Routiere - via Av.des Belges and Cours Mirabeau - to reach Place Verdun. Keeping 1 hr. for for the market.
 We would like to visit Atelier Cezanne next. Is there a good public transportation link from Place Verdun to the studio? I am not very keen on walking long distances!!
 Next we want to be on Cours Mirabeau for a late/relaxed lunch. We would also like to keep sometime to walk around here and see a beautiful architecture, especially some old facades with intricate detailing, beautiful doors, balconies and yes, of course the fountains.
Ideally, we would like to be at the TGV station by 5 PM. So, I suppose we would have to be on Gare Routiere to catch the shuttle back latest by 4?
Is this plan realistic? I have included my top 3 priorities in Aix, actually.
What else can we do in these areas to see buildings of beautiful town?
Looking forward to hearing your thoughts.
