They say the notorious Eastern State Penitentiary has the greatest number of "haunted" mentions on the site with 583.
The ranking also combines the number of "spooky" and "scary" mentions to get a total score.
Thrill-seekers can visit five haunted houses across the historic former prison's abandoned cellblocks and prison yards.
"Halloween Nights" runs on select nights through November 9.
Planet Cruise says the only place in the world spookier than Eastern State is Mary King's Close in Edinburgh, Scotland, a historic close, or alleyway, shrouded in myths and mysteries.
