So hard to decide, especially as Paris has some of the best queues of the Disney empire.
I love waiting for Phantom Manor, the very cool garden, the wonderful views of Big Thunder Mountain, the stretching portrait chamber, the hall of changing pictures! Love it.
Star Tours for a contender with all the awesome droids and Admiral Akbar! Awesome.
Buzz in the briefing room is very cool (the rest of the queue, especially outside is poor though).
Pirates of the Caribbean - so well themed, the very best in the Disney empire.
Tower of Terror, especially once you are in the hotel lobby, then the library, and the boiler room. A real work of art, as Disney should be!
