We waited an hour in October... the first time we got in line around 2, and then they said there would be a 20 minute break... we left... the line barely moves btw.. its really frustrating to stand in line while there is no line, or waiting for the other two character lines!!
The last day we had to wait, altho we did 2 character meals, Aurora wasnt at them, so for dd it was well worth the wait!! I have to say I was impressed, since the Princesses talk, and the other characters dont, it makes the "wait' longer, but it also makes your time with the Princesses special, magical!! They only take about 5 families in the Princess room, then you stop at each of the 4 (I think that's right, or is it 5 we had Snow White, Cinderella, Aurora... my mind isnt what it used to be!!) and each Princesses sat with dd autographed her book, talked with her, then she stood up to pose for pics, and they invited me in for a pic too, if you have the photo pass card, just hand it over and both you and the Photo pass team snaps pictures!!
good luck!!
