The Holly Hotel in Holly is widely reported to have some spirits, as well. That's got to provide strong cause for haunting. One has to wonder, on the other hand, how ghosts ended up at the Whitney. According to Hattis, the ghosts could have come from a variety of places. Indeed, he thinks David Whitney is one on the four ghosts living in the mansion.
Spirits can attach themselves to things.
Not that there's anything too worrisome about these ghosts. And trying to get rid of them would serve no purpose. And if they wanted to, they could make it so nobody would want to eat here anymore. The plush atmosphere, the furnishings and elegance. That's so tacky.
