I have been diagnosed with COPD and asthma and this is just my opinion and what happens to me. The smoke screen you go through at Pirates of the Caribbean will cause a problem for me as will the smoke machine at Bug's Life. The fountains in Epcot will cause problems as well if I stand to close or too long because of the Chlorine. I try to keep sugar free cough drops in my pocket or close by for when something triggers me. It seems to help. The scent at Figment is like skunky coffee, and it doesn't bother me. Philharmagic is a cinnamon smell, which I have problems with at times. It all depends on how "new" the scent cartridge in the ride seems to be.

I actually enjoy Soarin and all of those "smells"…

And I avoid Stitch because I just don't like the smell. Tell her to have as much fun as possible and try not to worry too much. Hope this helps….
