When we were there in May we had 3 to use as well. If you like Toy Story Mania at Hollywood Studios then you are DEFINITELY going to want to use one there. Even on a non-Extra Magic Hour weekday during a low-attendance time the stand-by line eventually built to 180 minutes....YOW!!! And at rope drop a long line built at the FastPass kiosks! The regular FP's were all gone for the day by late morning. We got some longing looks when we were able to use the special GAD FP machine to each get 3 TSM FP's! Because we wanted to hit all our favorite rides at MK and Epcot on our final day we used our other 2 at those parks.
