We are going one day to either Universal Studios or Islands of Adventure, and I am trying to choose between the two. We also have an 9 & 7 yr old and they are interested in both. But, I have a 3 and 2 yr old who loved disney in December and we need to go to the park that will have the most for them. Neither is a die hard Barney fan, so that is not a factor. Any advice would be great! Thanks!
