Parking at Poitiers Airport

[Fred]

Has anyone had experience of parking at Poitiers Airport for a few days?

I've been looking at their website https://www.poitiers.aeroport.fr/en/access/parking and it looks like you just park and pay when you leave.

I was hoping to book parking to make sure but can't find anyway of doing that, so I assume there is always plenty of room ?

Any info on parking gratefully received.
