Any suggestions on Disney with a child on the autism spectrum?

He may have invented a new drink-----dreamsicle au lait!

That's cute. It sounds like something my nephew would do. he also has Aspergers.
Margo and adisneyfan, thanks for the reports. The consistent thing I have noticed about WDW is that they are inconsistent. One time, a GAC gets handled one way and the next time it's differnt. We've had CMs tell us that Buzz Lightyear is not a Mainstream line (it is listed in the Guidebook for Guest with Disabilities as one). If you go twice to a ride during a trip, chances are good you will be treated 2 different ways. But at least they are trying.
