I must echo many reviewers, this place is great for people with younger children. We take our two year old twins every so often, and they really enjoy it. They especially love the dinosaurs, digging for "fossils," and the Egyptian area.
The price is reasonable, they even sell annual passes. You can print coupons from the website, too.
My only real complaint is that the bathrooms are yucky. And, Murphy's Law, my boys always need to go potty while we're there. Maybe they can upgrade or pay a bit more attention to upkeep.
