We saw Aurora quite a bit last week. She was in the courtyard in France at Epcot with only a few people around and we saw her in the Princess room in Toontown and also at the Princess Breakfast at Askerhaus.
Try going to the Toontown Princess room after 6pm. We went twice after 6pm and the lines for characters were MUCH shorter than during the day. We only waited about 20 minutes to meet 3 Princesses and that was the longest line. For Pooh & Friends and Mickey & Friends, the wait was only about 10 minutes. The Princesses we saw were Snow White, Cinderella and Aurora and it was very nice and un-rushed. Each Princess took time with my niece and chatted with her for a few minutes.
