That's what I have done - but it does mean you have to camp with the sound of racing cars for 24 hours - what not to like.
From previous years it’s just been Morgan Club France or VinMog that have had specific Morgan parking Areas. But expect you could get a car pass from the ACO and park on the infield.
I have always just left the car in the campsite as I couldn’t be bothered battling the traffic.
