la sirene ( Argeles sur mer )in the south of France had plenty to do for the older ones. The bar and night club was where most would hang out. If I remember they were careful about underage drinking. Which is good.

Lovely hot weather.

However I do think companies such as Keycamp and canvas etc do cater well for the older ones.

Good luck

Great time can be had at la Carabasse near Agde.
Great for the kids.. A bit of freedom for the adults.
