I would suggest that you are perhaps the one talking ******** if you do not feel that minimum rest, struggling to find a parking space
Surely an issue that may befall any car park no matter how close to the airport it is.
The only demographic that is changing here is an extra 5 minutes to your road journey to reach the car park. What is being said is if that 5 minutes makes or breaks a safe duty, then some other serious questions probably need asking long before the location of a car park becomes the sole cause of you going out of hours.
