I only have experience with Universal Studios in California, but my brother worked at the one in Orlanda and said it's basically the same.
In my opinion, it's for older kids, teens and adults.
The rides are mostly virtual, but they have a lot of jerking motions, and are loud. Some do have hieght/age restrictions.
They do have a few water play areas, games (like fairs have), restaraunts, characters, and maybe a few shows the little ones could go to, but all in all, most of the rides aren't geared for little ones.
