Yep..it's that easy at the airport..unless you are the first one off the plane..then you gotta figure which way to go..they don't always have somebody to point the way.
Don't panic if you don't see your driver at first. They can't park where you come out and they try to estimate the time you will be exiting. They never know if there is a long line at immigration and customs.
Also don't panic when you find them and they tell you to wait a few minutes and walks off. They are just going to get the car or van and will take a few minutes. The airport is a real stickler about parking and waiting..it's a no no.
