While I haven't been to Alaska yet I am a fan of ghost tours I have been on 4 so far. 2 here in Chicago, one in San Antonio exas and one in Plymouth MA. What I do is look up the port in a search engine with the word ghost tour after it, or look up a directory of haunted places eather on line ,try www.theshadowlands.net
or check a book at the book store or library in the paranormal occult section, then you can find out what sites might be haunted and visit them yourself if interested. Hope this helps.
