I have to say mine is how The Haunted Mansion smells like an actual “old house”. I grew up in New England, where’s there’s tons of houses and old buildings from the 1700s and the 1800s still standing, and they have that same district smell. I don’t even know how to describe that smell, but every time I ride The Haunted Mansion, I get flashbacks to my youth with that “old house smell”. I don’t know how Disney is able to recreate it so well, it’s just an excellent small touch that I doubt many people even notice. What’s your favorite subtle detail?
