I enjoy all the hate this place gets from childless adults. Once you have kids and take them places you will be amazed at what things actually grab their attention. I am not saying this place looks great, but it was designed this way for a reason.
For the crowd saying that six flags is where I would take my kids, you are missing the comfort of a place dedicated to families with little ones. As a parent it is so nice going somewhere and not having to worried about crazy teens and people swearing all over. You pick universal kids for a place where you can just let your little one run with no worries. Also going to a normal park with young ones nothing can kill their mood quite like looking at a ride only to tell them they are too small.
