Misspelling Writ Large. It survived the 9/11 terrorist attacks on the World Trade Center, but Hilton's hotel next to Ground Zero in lower Manhattan did not clean up the error of its name. "Millennium" has two n's. Think of all the towels, uniforms, stationery and signage that would have needed fixing. No wonder managers at the hotel claim the misspelling is deliberate to create buzz. Yeah.
