I saw something there, out of the corner of my eye. Was walking crosswise to a passageway and saw something white down the way, and it seemed to be moving.
Stopped, took a few steps back and looked again. Nothing.
Was probably just a trick of the light?
Ben, my niece is a pretty reliable person. I don’t recall how long she worked there, but she said that all of the tour guides she knew had similar experiences.
