I'd also say that Universal has diverged quite a bit away from just "thrill seekers". I was debating on taking my kids there for a few days during our next trip and my initial thought was there wasn't much they could ride. But when I made a spreadsheet of all the attractions, height requirements, etc... I was quite surprised to see how much there was for them to do. I think when discussing Universal folks often forget Seuss Landing, Jurassic Park (which has a gigantic play land, discovery center, and 2 rides kids can ride), and the fact that Marvel Island, while the rides are intense, has tons of fun characters and other things for kids to check out. Then over at USF, there is Shrek, Despicable Me, Spongebob/Barney/ET/Woody Woodpecker/Curious George area, Simpsons, animal actors, and of course both parks have Harry Potter, which much like Marvel has rides that are a bit intense for the typical kid, but they are still more than happy to go to Olivander's, ride the train, and buy tons of merch.
