We did the Chewie and Kylo meet-n-greets in April. As a previous poster said, they are fixed meet-n-greets. We were in line to go in the building when it opened at 10, which was pointless. We had a dining reservation to make, and had to get out of Chewie's line and come back later, but his and Kylo Ren's were the same length then as they were a couple hours later. Kylo's line wasn't that bad, we waited maybe 15min, and I didn't get the sense it ever got much longer than that. There is stuff to look at in the queue (light saber display etc). Be *slightly* forewarned, depending on your kids' ages (if you have them), that some are a little nervous around him. He is playing that character well!! My 7yo really doesn't scare easily, but he was slightly nervous. It's (bad mom) funny to look back at the photos b/c he nervously shoved his hands in his pockets as soon as Kylo approached us, and he never puts his hands in his pockets! The 10yo totally "got" that he was in character, so I'm just talking younger kids. Mine obviously rolled with it despite his nervousness, but I could see toddlers/pre-schoolers freaking out when Kylo comes toward them out of nowhere and has that scary-sounding voice.
