This is one of my favorite airports. There's a lot to do (it's practically a mall) and lots of restaurants. Also a Starbucks around every corner. But anyway, I don't mind having a 3-hour layover here because it's big enough to explore and there are plenty of tables in the main concourse to sit down at and work. It could stand to have more walkways for people who have to dart from one terminal to another with heavy luggage... or free wifi...
