Have a stop in Marseille on Tuesday, Aug. 22 (me, wife, 14 year old twins). Looking at a few shore excursions from same well reviewed company on Viator (8 person max tour) and basically it comes down to three tours which each offer visiting 2 out of the 3 of Aix,Cassis and Marseille so question is which two would you choose for a first time family?
(FYI - using Viator rather than direct booking as we have a credit to use . . .)
