PKI came right to mind for me, also. The Eiffel Tower, the fountains, the landscaped park logo, and the stone walkway with European-styled buildings lining the sides is by far the best first impression I've ever had at a park.
Of course, upon walking down International Street and seeing that a particular German building has been treated with Nickelodeon theming that completely detracts from the original style of the building, I am a little disappointed. Still, if that's the only thing Paramount screwed up in the International Street theming, I guess I can't complain.
