The general thought is it isn't worth it. We didn't hate it, but there could have been more done with it. There are a few threads talking about it already, you may find more info in them. For the Star Wars characters you get a form to rank your choices of 3 settings and you have to hand it in ASAP when you board. Choices are Dark Side which was Darth Vader OR Captain Phasma, Bespin which was Chewie or Boba Fett, and Tatooine which was R2D2 and c3po or Darth Maul. We got tickets to Bespin and the Dark Side. Captain Phasma was fun, apparently scripted but she commented on my daughter running around in circles. Hubby got to meet Boba and it was just pose and be done. There are also Jawas, sand people and Imperial Officers walking around during the day on decks 3,4 &5. Storm Troopers on deck 4 outside and on deck 11 at certain times, and Boba Fett would make an appearance looking down on the crowd.
There was more going on, but the Jedi training was a disappointment for many and has apparently been changed to include more kids. Just remember to wear close toe shoes for it or they have no chance of being chosen. Our guest speaker sucked but the last couple have been cool behind the scenes people.
