I wonder if anyone can confirm or correct me with the following information: There are trains going to Aix Center (Gare Routiere). I have been two Aix twice before but drove. If I remember correctly, Gare routiere is about 5 to 10 minute walk to Cour Mirabeau.
Also, should I book the tickets now or just buy them at the time of travel. My flight will be arriving around 8:25 in the morning. Many thanks in advance.
