End of August we're off on a road trip to Ile de Re near La Rochelle. I haven't had our Model S over in France during the summer, and wondered if anyone had any experience of how busy the Superchargers get? Specifically I'll be routing thru Mont Saint-Michel, Nantes, Poitiers and Le Mans. I've sorted destination charging as there is destination charger a 3 minute walk from our Airbnb, but just wondering if I should plan in some time for waiting for a stall. Many thanks.
