This airport is a gem for international travellers. Get off plane, only people in line at customs are people on your plane! I once waited in line with a whole 10 people
If you don't have friends/associates picking you up, GET A LIMO! The expanse is not terribly greater than a taxi, but you can strech those legs after your plane ride.
Make sure to swing by Reilly's Daughter in the back right of food court for a good pint of Guinness. Ask for Boz and then ask him about all the famous people he knows like Jenny McCarthy.
