We've seen both separately on 2 different trips. We never seen them listed in the time guides as meet & greets. We pretty much just came upon them. We saw Miss Piggy near the Fountain in front of the Muppetvision theater. The next trip (last spring) we saw Kermit in front of a mural painting (I think it was a pic of a gazebo) to the side of the Muppets gift shop. No lines either time.
