"I am in the queue for [Rise of the Resistance] – someone let their kid take a dump on the floor and then they just walked out and left it- WTF?," starts one thread from a couple months ago.

Two former Disneyland custodial team workers have also written about this unsavory topic in their book "Cleaning the Kingdom: Insider Tales of Keeping Walt's Dream Spotless."
