Cannes
The artist is right, the HLS is on the pier, I would not be shure how to get approval, ask Mandelieu or the Chambre de commerce.
It is also not the non published site at the casino.
Cannes LFMD, is quite convenient, heli friendly (straigth approaches etc) and has full service and reasonable opening times. Remark that for the AIP site flotation gear is required.
