The entire park is beautiful. The best piece of information I can give a person going to the park is regarding the express lines. If you stay at one of Universal's two on-site hotels, you don't have to wait on the long lines with everyone else, you can go to the express line. The most we waited was 10 minutes on any ride. If you are not staying in the park, when you get there you take your ticket to the express machines located outside each ride, you put in your ticket, and get a time to return to the ride via the express lane. Wonderful system. I don't know if they have figured out how to do this at Disney yet, but I plan to find out (and hope they have!).
There is a section outside of Universal Studio's called City Walk. Here they have a bunch of restaurants and bars - something suitable for any age. We really enjoyed our vacation.
