01.Copper Queen Hotel // Bisbee, Ariz.
Completed in 1902, the Copper Queen is Arizona's longest operating hotel and, according to hotel visitors and employees, it's haunted by more than 16 entities. Perhaps the most famous of these is Julia Lowell, a prostitute who worked on the hotel's third floor in the 1920s and '30s. Legend has it that Lowell fell in love with one of her clients but was rejected and now she haunts room 315, appearing to guests as a cloud of white smoke, or sneaking up behind them and whispering in their ears.
02.Biltmore Hotel // Coral Gables, Fla.
The Biltmore has a lengthy, troubled past. During the roaring '20s, the hotel was the place to see and be seen host to wealthy socialites, celebrities, and some pretty notorious gangsters. But in the '40s, the United States War Department shut down the hotel, converting it into a hospital to treat wounded soldiers. By the '70s, the building was completely abandoned, left crumbling and in disrepair (check out the 1977 B-horror film Shock Waves to see it and its counterpart in Palm Beach in their abandoned states). Nowadays, it's once again a luxurious hotel but it hasn't left its past behind: guests report sightings of past residents, most famously Thomas "Fatty" Walsh, a mobster who was killed over a gambling debt in the hotel in 1929.
03.Colonial Inn // Concord, Mass.
With a history dating back to 1716, the Colonial is said to be haunted by none other than Ralph Waldo Emerson. Other guests report experiencing "phantom presences" in Room 24, once the operating room of Dr. James Minot.
04. Bourbon Orleans Hotel // New Orleans, La.
The Bourbon Orleans Hotel has only been a hotel since 1964. Founded in 1817, it has alternately been used as a ballroom, legislative meeting place, and convent. Now considered one of the most haunted hotels in New Orleans, it's believed to be occupied by the ghosts of confederate soldiers, Catholic nuns, and the children who lived at the convent orphanage in the 19th century.
05.Hotel Andra // Seattle, Wash.
Seattle's Hotel Andra is home to an eternal party of jazz age ghosts: It's said that 1920s partygoers are often heard playing music and breaking glass on the hotel's ninth floor. But when anyone ventures up there, the noise is immediately silenced.
06. Captain Grant's B&B // Poquetanuck, Conn.
Carol Matsumoto, who runs Captain Grant's, reported hearing loud knocking sounds before she even opened the historic B&B. The house, which was originally built in 1754, is said to be home to several colonial-era ghosts. Guests who stay in the B&B's "Adelaide" room report seeing a woman holding hands with two children all dressed in colonial garb standing at the foot of their bed. 07.Gadsden Hotel // Douglas, Ariz.
Ghost sightings at the historic Gadsden Hotel are so common that guests are invited to write their experiences in two binders kept at the hotel's front desk. Visitors report having their hair pulled, their televisions turned off, and even being pinned momentarily to their beds, unable to move. Hotel manager Robin Brekhus, meanwhile, insists she's seen the ghost of a cowboy in a long duster coat on a trip to the basement: "It was like he wanted me to make eye contact with him and acknowledge that I saw him," she told Reuters.
08.Hotel Monaco Alexandria // Washington, D.C.
Located in the city's historic district, the Monaco dates back to the Civil War, when it was known as the Marshall House. It's said the ghosts of James W. Jackson and Colonel Elmer Ellsworth, both of whom died during the war, haunt the sixth floor.
09.The Omni Grove Park Inn, Asheville // Asheville, N.C.
The Omni Grove Park Inn is said to be haunted by a mischievous ghost known as the Pink Lady. Though her origins are mysterious, she's supposedly a friendly ghost who delights in pranks rather than frights: She occasionally appears as a pink mist but spends most of her time invisibly turning air conditioners on and off, tickling guests' feet as they sleep, and even holding their hands.
10.French Lick Springs Hotel // French Lick, Ind.
Indianapolis Mayor Thomas Taggart bought the French Lick Springs Hotel in 1900 - and though Taggart died in 1929, it's said that his spirit never left the hotel. His ghost still lingers near the service elevator, and he's even been rumored to help operate the lift when things get busy.
