Terminal 4 is probably the easiest place to fly in and out of! Having the departures on the south side and arrivals on the north side helps ease up on the traffic circling around the airport. I often park at the high profile lot because of the conveniency to the doors when I pick up the hubby. Our favorite thing to do is to try to surprise him by hiding behind a column or walk while he approaches the waiting area. Great pointer, if you can make it back to your parking under 10 minutes, it's free. Otherwise plan on spending $1/hr or $20/day.
