I have kids 8,6,4 and we just went. They loved it all---I'll tell you favorites and the ones(very few) that they wished they hadn't done.
Favs:
DD8: Rockin'Roller coaster and Primeval Whirl
DD6: Space Mntn. and Peter Pan
DS4: Jungle Cruise adn Buzz Lightyear and Big Thunder
All of us: Mickey' s Philharmagic

and Soarin'
Avoid: DD6 cried on Honey, I shrunk the Audience--A big snake comes out
and DS4 cried and screamed on Dinosaur---way too scary for him. (I hope I didn't scar him for life

) DD8 said she didn't like Test Track at all, but went on it twice more and still stuck to her story
Donald's Brakfastasurus was the best meal for all to enjoy--lots of laughs.
Your 1 yr. old will like most of these and anything with a height requirement, you can baby swap. She/he will love Dumbo and parades.
