Honeymoon south of France

Hi! We are planning our honeymoon last 10 days of August in the south of France. We have our last accomodation booked for Ville Franche sur Mer for 4 nights, and flying in and out of nice. We are looking into where we should stay for the first five nights.

I was thinking 2 days in Antibes, train to Aix and 3 nights in Aix ( we want to visit wineries and stay in a cute chateaux) What do you think of this plan or do you have any better ideas?

Thank you!
