The storytime was cute. A princess comes out and tells her story.
We took DS, and wow it was a long line. But he wanted to meet princesses, so it was worth it for him and us.
After, he didn't want to leave so we sat for the storytime, which seems to happen often. And he was chosen to dance with the princess, who turned out to be Sleeping Beauty, and if you wish to, my December trip report (link in my signature) has some pictures that I took of that.
I think if DS wanted to go again to meet them, I'd go first thing in the morning when PFF opens. That way the line might be shorter and the payoff might feel better.
Just don't let your kiddo get "set" on seeing any one princess, because they change in the meet and greet. While we were in line, we saw Cinderella and Prince Charming leave, which upset some kids. Then when we were next, we were told that Mulan was there, which we were excited for. But then just as we got in, she left and Pocahontas took her place. So don't let yourself get exciting for a particular princess, just try to make sure the child is open to anyone, and it will be better.
Over Belle and Pocahontas, my guy liked Princess Minnie the best.

I think it's b/c she wasn't wearing lipstick.
