I've never gone, but I perosnally think it was a waste of money. Why pay $15 to see cement dinosaurs when you could pay $50 to go to animal kingdom or Islands of adventure, and see animatronc dinosaurs, plus the rest of the park.
I'm not 100% sure on this, but I think Dinosaur world might have closed up. On my last trip to bush gardens, (dinosaur world is along I$), there were a bunch of dinosaurs laying on their side in a pile in plain view. It didn't look very welcoming.
