My 4 year old actually loved tower of terror but most young kids probably will not want to ride.
If you have lil ones don't miss Disney Junior Live Stage
All except tower of terror and rockin rollercoaster could be seen as smaller rides or easier attractions. Especially if your asking for children involved. There are plenty of smaller shows and attractions plus tons of street shows.
Don't miss Fantasmic! Its a great show.
Toy story, the star wars star tour ride and all of the shows are great
