I only know from our experience when we were there back in January (I asked CM at City Hall where Woody and Buzz were...my DS's favorites, of course). She said Woody (and Jessie) is mostly by Big Thunder Ranch and Frontierland areas, and Buzz is now only usually seen in the Pixar Parade at DCA. That was from our experience anyway, but I'm sure others may know more or maybe it's different now. Hope that helps!
