Dubai International Airport is nothing short of palatial. It's Terminal 3 building alone is 18 million square feet and was the largest building in the world (by floor space) upon its completion in 2008.
For passengers, that means there are going to a slew of available shopping, restaurants, spas, and even sleep pods. For the young ones, there's a dedicated kids zone complete with interactive games, family-friendly entertainment, and a climbing area.
