For some reason, I thought your child was two - sorry!! All of my suggestions below are for two year olds, not 8 months. However, a lot of them could still be enjoyed by a baby.
Here is my opinion on what your little one will like. At US - Barney Show and Barney playground, Fivel's playground, Curious George Playground, ET (maybe, there is a loud police scene right at the beginning but after that it is very peaceful and fun), Shrek and Jimmy (maybe in the stationary seats), Animal Planet Live (maybe, I haven't seen this one personally).
At IOA, The Cat in the Hat (this spins a lot, but I think you can have the spin mechanism turned off) One Fish, Two Fish, The Caro-Suess -El, and If I Ran the Zoo Play Area. Discovery Center, Triceratops Discovery Trail, Camp Jurassic, Me Ship the Olive play area.
Also, depending on your child there are a lot of opportunities to meet characters - Scooby and Shaggy, SpongeBob, Curious George and the Man with the Yellow Hat, Jimmy Nuetron and other Nicolodean characters, Popeye and Olive Oil, and the Super Heros.
Also, pack a swim suit for the wet play areas, otherwise your little one won't be able to enjoy those areas fully.
I hope this helped you.
