We made a pit stop at Dinosaur World about 4? years ago. We were flying in/out of Tampa and staying in Orlando. Our favorite place to stop for lunch is at this exit - the Branch Ranch. I highly recommend this place. Very yummy. Not a cheap lunch, but not expensive. You get very good homecooked food with homemade pickles on the table. Yum!
Anyways, Dinosaur World was a perfect stop for our young son (?5 at the time), especially if your child likes dinosaurs. Lots of replicas with facts about each one. They also have a dig area and a place you can dig for treasures that you can take (they say dinosaur teeth - sure looks like shark teeth to me!). It was a good way to kill a few hours. I don't know if I would make a special trip but it was okay since it was on our way. Looks like they have lots of boy's bday parties there. My son liked it.
