My sons 11, 13 and 14. didn't care for it much. We went only because we had the options package. We went twicee and stayed only 2 hours each time. We may have stayed longer but we went after dinner(and a day at a park) Kids didn't think it was worth the admission price at the door. The kids felt the video games were old and many weren't working. They did enjoy designing your own rollercoaster ride-then you ride it in a simulator, but it took a long time. They also like the Buzz Lightyear game. That was just their thoughts but I know some kids that thought it was great.
I think every one needs to make their own decision. I wouldn't pay full price. If you are wanting to do the water parks, get the options package and DQ is an option you can also do.
