Its a brisk pace and i wouldn't bring people in tow as im a fast walker. So long as you are not dragging a steamer trunk its doable, but i would make sure to have at least two hours free time between flights to actually enjoy your food and then be able to sit in the nearby greenspace to watch the planes land. You can actually take the parking lot shuttle next door which i think is "The Parking Spot" and then walk back and save a few steps..
