Yep, Buzz is like #1 on our list too.
You know what I did, and it may or may not work for you. I got out my copy of Unofficial Guide and it lists all the attractions. Or UG for Kids would work well too. I sat with the kids (okay, I was sitting, they were on the computer and playing Wii)

and went thru the rides one by one just to get their input about them. I made sure to explain if they were loud or dark or wet. We'll be at WDW long enough to see everything, but I just wanted an idea of what they were most interested in-- to help me make a game plan-- and wasn't sure if my guessing would be right.
There are also videos of almost everything on
YouTube.
For the most part, I would have guessed it right. But not all the way. Cinderella's Carousel might work well for some kids, and mine like carousels, (going in circles is fun!) but my boys are both at the age that if it sounds "girlie" they want no part of it. My youngest (8, autism) wants to go to Playhouse Disney Live at MGM, and I would have pegged him as too old for that. My oldest, I tried to explain to him that Mission: Space has been known to make
adults puke, and that completely backfired cause now he really really wants to go on it! (and will be going with his
father)
It's hard for them to say what they'd like and not like sight unseen, but I did get some feedback.
