meh- my 3 1/2 year old like Tower of Terror.
I forgot about star tours. He liked that too, but we didn't use a fast pass for it. That's a good option too.
Muppet vision we walked right in and sat down.
Disney Jr, we stood in line maybe 20 minutes. The nice thing about a fast pass for that one is you can probably get in sooner and located a good spot in the middle of the theatre. You don't want something to close or too far away.
