There may be scraps here and there at Disney but honestly, with the volume of people there, they do an amazing job keeping it clean. I recently visited our state fair just days after our Disney trip. Talk about trash! My husband said the men's restroom was like a 3rd world country. I've never encountered that at Disney, thankfully! I stepped on a cheese curd in the food building, my friend's son had super dirty feet at the end of the day (wearing flip flops), none would happen at Disney. Pretty clean place, imo.
