Hi Jory!!!
Thank you very much for your question to the Walt Disney World Moms Panel!!!
I have an almost four year old son so I will speak from experience on what he likes. First of all, he loves both parks, which I am sure that your two children will as well. There are attractions and shows that children of all ages can enjoy at each. It does seem like our son enjoys spending more time at
Epcot than he does at
Disney's Hollywood Studios.
His favorite ride at Walt Disney World is Soarin', which is located at Epcot. He also loves Test Track, spending time at the Seas with Nemo and Friends, riding Living with the Land, and Spaceship Earth. He also loves running through each of the
Innoventions Pavilions. They are each so interactive and educational!!!
We are sure that he will eventually start to love Disney's Hollywood Studios the way he does Epcot once he gets older. Once he is able to ride The Twilight Zone Tower of Terror and the Rock 'N Roller Coaster starring Aerosmith, I have a feeling that we will be spending a lot more time at Disney's Hollywood Studios!!!
Thank you again for your question! Please let me know if you have any other questions!!
Have a magical trip!!
Scott
