No...well, sometimes. DDE can be used at some CS locations where there are not TS restaurants. For example, the discount is good at Tusker House, Flame Tree, Restaurantosaurus, and Pizzafari in Animal Kingdom. It's also good at the All Stars' Food Courts, and Sassagoula Floatworks/Food Factory (POFQ). You didn't ask, but it's good at resort lounges, too. We got our money back on this deal withn 2 days!! Hope this helps.
