Things to see near Orlando and Vero Beach

[goofy4wdw2]

We always fly to Disney but we're planning to drive (from Philly area) to Vero Beach and Universal in August for our daughter's 10th birthday (she's a huge fan of Harry Potter). Since we'll have a car we are wondering if there are any other spots along our way or close to Vero or Orlando that we should see. I'm thinking maybe the Kennedy Space Center. Any other ideas? Our kids will be 10, 7, and 4. Thank you!
