Apologies for this not being obviously organistic . . . on the other hand going to an orchestral concert can give one a wider appreciation of organ registration.
The Orchestre Régional de Cannes is quite superb http://www.orchestre-cannes.com/
and in the Evénements section you'll see find the list of forthcoming events, which are temptingly exciting.
It's so easy to go to a holiday destination and miss out on great cultural activities nowadays patronised only by the cognoscenti locals. For my part, one of the influences in my life was for three memorable years of years of youth between 6 and 9, going to the outside concerts of the orchestra at Menton on warm summer evenings.
It's for this reason that it's SO important for children to be taken to such events instead of being disenfranchised on account of "not being interested in that" . . . Take them, and they might be!
