The right sunshade will keep your car cool and make it look cool as well If you have a car at Walt Disney World and you have a sunshade for your windshield, you might want to use it. There is little shade in the theme park parking lots, and the temperature inside your car will reach a level that you never thought possible. Even if you are planning on hitting the park from open until close, use the sunshade. You might decide to park hop or leave earlier than expected.
