They have a really cute new girl themed area and many of the rides are cute and fun. 4 years old is a good age (though I think there is one or two rides she might not be tall enough for). If she's into Legos, it's a fun park. It's much more scaled back than Disney and not as heavily themed. The rides are much shorter, more like a local themepark. We went in Sept, and it was very hot (there's not as much shade, no misters, etc.). I think it was the hottest park we went to that week. I have two boys who both loved legos, so this was their favorite, but I was kind of unimpressed. It's kind of a longer drive (45 minutes +) so if she's not into Legos, I would choose something else because it will not seem as "cool" as Disney.
