I visited a car park in Barnsley today. I arrived at the same time as a family yet I had to pay the same as 4 people. Is it fair? Yes because you pay per car just like you pay per booking at EZY. Get over it.
one car (with four people) = one space
one car (with one person) = one space
four people on plane = four seats
... however,
one person on plane = only one seat
simples
