Ok, perhaps this is not a topic anymore. Then I will stop it at that:
The official information has been published yesterday, on the prefecture website (unfortunately only in French.)
It states that a sticker will only be needed to enter the area, not if you are already inside. Therefore, there should be no pass needed starting from the camp.
My father and I will try to join at Pegasus on the 5th. Good luck to all with your Normandy trip! Céline & Bernard.
