I was informed that the snow on Main Street now smells like cinnamon. I didn’t stick around for it. The cast member pointed to the top of the poles and suggested I avoid standing near them.
Regarding Small World, my family indicated they definitely smelled various country smells.
The funny part is that no one mentioned scent in Haunted Mansion, and I actually didn’t smell it at all. My friend told me yesterday morning (the day after I went) that there’s a gingerbread smell near the gingerbread house in there, but it didn’t affect me. The ride stopped several times while I was near it, so I wonder if it was having a mechanical problem, or it’s just faint enough that it wasn’t an issue for me. I did have a headache yesterday, but I think it was probably just related to fatigue.
