“So simple. Put address in your sat nav. Number plate recognition on arrival, gate opens and an employee directs you to parking space.
Gives you a ticket for return bus back.
You park and take.own keys so no joy riding whilst you are away.
Hop on the bus and it takes you direct to departure door.
On return wait at bus stop where you were dropped off. In case you have forgotten where you have parked information is on your bus ticket.
What could be cheaper and easier”
