Well, for a Fall program, the air conditioning is not such a big deal in contrast to a Summer down here. However, Epcot and MGM are the most likely places where you get some cold air.
Soarin', M:S, TT, Energy Adventure, Living Seas, and JII are all largely indoors. There is a greeter that is outside, but you get bumped around every 2 hours or so. With Soarin', even the fastpasses are indoors. Attractions also includes things which aren't rides. So there is Innoventions for example which is all indoors.
With MGM... Star Tours, ToT, RnRC, etc.
If you want to move around a lot. Work something like Fantasyland Ops or Tomorrowland Ops. Might be working IASW one day, Peter Pan's flight the next day.
