I haven't noticed any styrofoam coolers at the resort or park gift shops. On our last trip, we packed a soft sided cooler with snacks, instant oatmeal, styrofoam cups, spoons and a hot-pot to use in our room. We checked it as luggage for our flight. After all the snacks were gone , we were able to fill it with our extra purchases (refillable mugs, etc.) to bring home.
