Another vote for Peter Pan.
We rope-dropped Peter Pan two weeks ago, and we waited more than 10 minutes even though we were near the front of the rope-drop crowd. We had to drop off our stroller, and in that time, easily more than 100 people got in front of us.
On our next MK day, we FP+'d Peter Pan, and the wait was about 3 minutes.
Also, you can see people getting on the ride during the entire FP line, which is more entertaining for the kids. On many other rides, FP does not help you a ton, but on Peter Pan, it is amazing.
Our DS3 loved the interactive queue at Winnie the Pooh, and he was disappointed to ride it with a FP, which skips the interactive queue entirely.
