there is mini air conditioning units inside the charactor costumes because i have seen on many shows about disney that there are. if you just look online a little you will see that there is already a costume that has an air conditioning system in it. it may still be true that people have fainted inside costumes because of the heat but that does not mean that the costumes dont have those mini ac units inside them...all it means is that the ac unit is not nearly enough to cool down the costume on a hot florida day.
