Honeymoon in south of France?

My fiancé and I are looking to do a 10 day honeymoon in early June in the south of France. I’m looking for honest review on the following things: – Is there enough to do to fill that many days? (we do not drink wine) – Will the weather be nice enough for the beach? – Does it require a lot of walking and physical activity to see and do everything? I have a chronic illness so I can’t do crazy European vacations like I used to where you’re out walking all day.

Bonus points if you can give a brief description of each town/location and what’s to see there.

I’m nervous it’s overhyped and will just be crowded and filled with tourists.

Thank you!
