This is Disney World, and surely characters will just be strolling through the park greeting children who happen upon them, right? Wrong. If your kid is dying to meet Mickey, Minnie, Anna, Elsa, or really any of the princesses, you're going to have to wait in line . . . even if you have a FastPass+. If you didn't score a magic line-hopping ticket, you'll probably be able to catch those characters at a parade, performance, or fireworks show from afar.
