The Denver Gazette reports that since Stanley's death in 1940 his apparition has reportedly appeared to guests checking in at the reception desk, and that the phantom of Flora Stanley, a pianist, is sometimes heard playing in the empty music room 4. The same account collects guest descriptions of shadowy figures, laughter, flickering lights and objects moving on their own in every room of the hotel compound 4.
After Elizabeth Wilson's death, the Gazette reports, the hotel began receiving accounts of a spectral chambermaid hovering and passing through closed doors in the rebuilt guest quarters 4. The paper describes unmarried couples complaining of an invisible force wedging them apart in bed, and single men finding their bags packed outside the door, behavior that tour guide Richard Estep attributed to "Mrs. Wilson" 4. It also reports numerous sightings of spectral children on the fourth floor, the hotel's former attic, and adds that records show no child ever died there 4.
Room 217 is the hotel's most requested room, according to the Gazette, which reports the claim that it drove Jim Carrey to leave in the middle of the night during filming 4. The paper says the campus has hosted many paranormal investigations, including teams from Travel Channel's Ghost Adventures and SyFy's Ghost Hunters 4.
Estep, a paranormal investigator and author who led weekend ghost tours at the hotel, told the Gazette he considers the Stanley one of the more active locations he has investigated 4. He also told the paper that old doors and frames, and wind moving through a century-old building, explain many supposed encounters 4. The Gazette reports that hoaxing is a fireable offense for hotel staff 4. The hotel's own ghost tour page says the night tour covers "the most active locations" and presents "documented hauntings" alongside folklore 5. Visit Estes Park states that the hotel has earned a paranormal reputation and offers a night tour of "active phenomena and spirit folklore" 3.
Visitors commonly describe footsteps and running in the fourth-floor corridors at night, knocking on doors with no one outside, and closet and bathroom doors in the guest rooms found open after being shut. Guests on the night tours report cold drafts in the underground tunnel and the concert hall, faint piano notes carrying from elsewhere in the building, and lights and faucets turning on without anyone near them. A number of accounts are less dramatic: guests who spend the night in the older rooms and report nothing out of the ordinary.
