Here is the bad news, sigh, Disney not only uses scents in rides and shows but in shops, parades and other places. They are called
smellitzers.

I get puking ill when I get around certain perfumes and aerosol sprays and have gotten sick on bathroom sprays at home. If you have a major reaction to heavy perfume on people then consider getting a GAC. I rarely have been stuck with perfume hogs and when I run into one I move away or cover my face with my shirt or stand with my back to them.
