The restrooms have been rather good lately it's the guests that are throwing stuff anywhere they want where the rest of the world is horrible. the amount of visitors that can't move their trays to the garbage can and then the wind blows it all around or just don't care and toss stuff on the ground as they are walking. Part of this I know is the cut backs where all the cast members aren't moving around the place the same way to discover and deal with it so there is less non-guests to notice it.. restroom wise, it's really overflowing trash bins that seem to be mostly at the end of the night when people are leaving or after some massive lunch rush, but I also see the castmembers there dealing with it so I don't call that unclean. There is somethign wrong with the sinks though, you seem to need to put your hand over the back of the sink to trigger water coming out of them to wash your hands and that's getting water all over the counters. then the towels to dry your hands are over those counters so your towel gets wet and just makes a mess.. not really a guests fault, it's just bad design in how disney put in the new motion sensor hand faucets.
now if I'll sit on a toilet is entirely different than if I find the restrooms clean. That has other ramifications and I don't treat it like my home toilet where I know everyone and what i'm coming into contact with by doing it....
