Sorry last post posted before completed what I was saying
Take 2
It takes the same amount of time to collect somebody as to dropping off.
Original post was all about collecting a passenger in the evening, it's a lot easier to park a short distance away for ex airport hotel, then when your passenger has arrived on level 5 get them to call you on mobile and you will be there in 2 minutes, passengers are waiting to be collected and you're away again just as quick as anyone dropping off.
now try getting into the arrivals collection point at the same time you will be stuck in line then struggling to get a spot to pull over to collect your passengers, level 5 in the evening especially after 8/9pm is disserted
