Hopefully Rise will help not just by being an incredible ride but by actually featuring the characters. Now I haven't actually been to Galaxy's Edge yet but my understanding is so far the only actually featured pre-exisisting characters are Chewie and Hondo on Smuggler's Run and Rex in the Cantina, with Rey, Kylo and The Storm troopers as walk-around/meet-and-greets. Correct me if I'm wrong.
Now having walk around characters are great but they are unreliable, you never really know if they will be there. It's part of why it is so important to have familiar characters in the rides. We already know that Rise of The Resistance will have a bunch of Storm troopers and an encounter with Kylo Ren is all but confirmed at this point, but what about the others? Will Poe and Finn give us our mission at the start, will we see General Hux giving orders on the Star Destroyer, will BB-8 and Rose commandeer our ride vehicle, will Rey save us from Kylo? I certainly hope so, not just because I love these characters but because after spending a few minutes on a thrilling adventure surround by familiar Star Wars characters will help sell the illusion that this Star Wars land really is a Star Wars land.
