I'm not the person you asked but for many families with small children they only have one option...Toy Story Mania. The others have height requirements. The only other attractions in the park are shows, which small children are not known for doing well sitting through

Hollywood Studios is just not the greatest park for families with small children right now. I do hope that changes (to the effect of more rides for small kids without taking away things that interest teens/adults). If nothing new is added for small kids before we go back in 2016 it is pretty likely we will skip that park.
