2. Drink Water, Lots of Water
People tend to underestimate how big Animal Kingdom is (580 acres!), and how sunny and humid it can get at times. You're going to do a lot of walking and sweating here, so be sure to drink a lot of water to compensate. You can bring your own as long as it doesn't have a plastic drinking straw, or you can get free cups of water at many counter-service restaurants.
