We will be taking train from Genoa after 12 days in Italy. Have 12 days for south of France and Paris. A little background, have been to Marseille, Aix, Avignon and a few surrounding towns in that area. Planning on car rental at some point. Menton? Maybe better car pickup in Nice? Also, thinking of the following: Menton--2 nts, Aix--6 nts, and Paris--4 nt.--which we have been to before.
Stay in Menton or Nice or Antibes before Aix? Other ideas? I know I am leaving out a lot of details on interests, etc.
