Take her to the coronation ceremony. The times will be noted in the times guide. Last week on Monday, Tues, and Weds, the coronation ceremony had Cinderella, Aurora and Snow White. They have some of the Court come out and teach the girls to wave and a little dance. Then the three princesses are introduced and after they are all there, the girls are led in what they have learned with the Princesses. After that they bring 3 maypoles out and the girls walk/dance around the maypole with one of the princesses. They then leave the stage and have everyone clear the floor. A lot of people think that is it and leave; however, once they get streamers picked up off the floor, the Princesses come back out for meet and greet. Seeing and taking pictures Cinderella after the coronation took us about 5 minutes. The Fantasy Faire Princess "line" was an hour. Sure we had to sit through the coronation show, but DD loved that part so it didn't feel like waiting.
They also were doing the story time, but we didn't hit that one so I can't tell you much about it. Again, the times were in the times guide.
Those same three days, the Fantasy Faire line was for either 2-3 princesses, and the possibilities were Ariel, Belle, Mulan Tiana, Ariel or Jasmine. When we went through the line, we got Mulan, Ariel and Belle. Actually, we did the line Sunday, so I guess there were the same options that day too.
Rapunzel as a previous poster said is in Fantasyland along with Flynn Rider. You can't miss her spot, you will see her tower and hair. The entire time we were there, her meet and greet started at 11:00 a.m. Just a warning, I got there 10 minutes before the line opened Monday June 6, and the line was already close to 2 hours. I went back 30 minutes before the line opened on Tuesday, and the line was an hour (for after it opened meaning we waited one and a half hours total). I was wishing I had done it on Sunday because the line was only 45 minutes when we passed by that day (the parks were much more crowded Mon and Tues, than they were Sat. or Sun), but we were on our way to a 1:00 p.m. lunch reservation at Ariel's and did not have time to stop. The CM told us that 45 minutes is usually the minimum line. Wednesday, the day after we stood in the long line, the parks were less crowded and the line was 45 minutes again.
