Taking 2 kids, ages 6 and 10 to Universal Studios late June. Need help please! Does it warrant a whole one day there? Also, what would you recommend seeing? Any necessities to bring? What about food? Any good, not expensive place to eat? Also, should we do islands of adventure too or is it too much for one day? Sorry for all the questions. First time at any Disney park, we are newbies! Any help would be greatly appreciated!
