We spent the entire day at Universal Orlando Resort absorbing as much as humanly possible. I posted a separate review for Islands Of Adventure, so this review is specially related to Universal Studios.

My recommendations:

Take the Hogwarts Express (If you have a two park pass)
Toothsome Chocolate Emporium (Order a shake)
Harry Potter and the Escape from Gringotts
Visit Diagon Alley
Horror Make-Up Show
Race through New York with Jimmy Fallon
The Simpsons (Do everything imaginable)
Revenge of the Mummy

And that's just the tip of the iceberg.
