I am not quite sure what you are asking, OP?
Also Universal Studios is in Universal City. Now technically speaking Universal City is IN Burbank not many people associate the two. They either state it's in Universal City or Hollywood.
There is no Islands of Adventure in US/Hollywood. No Harry Potter either.
But US/H is tons and tons of fun! Many fabulous rides! And there is CITYWALK as well for all your souvenir shopping and loaded with restaurants!
