none of my kids have ever been scared of HM, and they all rode it, except oldest ds, when they were toddlers/preschoolers. My niece is another story! That child is afraid of everything, even refuses to be in any room of her own home alone, and no, she's never been in any situation that caused this, she's always been this way. Last fall she totally freaked out before ever getting inside the mansion, to the point that another niece became hysterical along with her. She's 7 now and still works her way into hysterics if anyone even asks if she wants to try it yet. Unless you have a child who over reacts like my niece, you probably won't have any problems.
