We are going on the Rick Steves' tour Best of Eastern France which ends in Aix-en-Provence. The tour includes only 1 night there, but we have added on 3 additional nights, so we will have all of Saturday, Sunday, and Monday on our own. (Tuesday we take the train back to CDG).
I've heard that the markets in Aix are great, and Saturday is a market day, so there's that. Other suggestions? We could rent a car if that helps.
Thanks in advance for your help!
