We were there last year, and it was great! DH and I did the Star Wars Millionaire (usually the first two shows each day), and if memory serves me correctly, it's the same kinds of prizes as the regular play (pins, hats, tees--but Star Wars themed--and the
Disney Cruise when you win 1 million points). I can't remember any of the questions off the top of my head, just that when it got to about 8,000 I didn't know the answers. DH ended up fourth on the listboard at the end of the session (he wouldn't share the answers). Oh, and they had Gammorean (sp?) Guards in the audience and kind of played them up. It was fun.
If you wanted to do any of the meet and greets, last year you had to get a fastpass to get autographs and/or pics with the celebrities. Last year they had Peter Mayhew (Chewbacca), Jake Lloyd (little Anakin Skywalker--who was not so little anymore), the actor who played Boba Fett (can't remember his name) and others I can't think of right now. The fastpass pick-up area for the meet & greet was at the Millionaire fastpass machines. The celebs also were in the parades, which made for better photo ops with no waiting.
They had a Jedi Training Academy near the Star Wars ride for the kiddos, and each hour 1 or 2 of them were picked to battle Darth Vader or Darth Maul!! It was neat to see some of these kiddos so excited to do them in!
HTH!!
