My wife is weird lol, she goes to the parks and will hardly ride anything anymore and still have fun. She didn't mind walking around and just enjoying the park while we rode with her keeping an an on the little one when had already. I will say that my wife has said she doesn't really want to go back to Universal or IOA until the girls are older since there isnt too much for them to do at such a young age, but also she said the same about Hollywood Studios.
I agree, Universal can use some rides with no height requirements that the whole family can ride.
