Well, I am willing to put up with a napkin on the ground for an extra few hours before a ecology staff can get around to cleaning it up, than having to pay Disney price to get into the park!! That is reason I have only been to Disney once in my life. CF I believe, has spent some money to help keep KI clean. There is a breaking point on where to spend you money. Mainitain rides and build new ones, or have a cleaning person that can clean up a used cup left on the ground in 15 seconds of being dropped.
