Isabel, the huge Little Big Planet Fan, searched online while playing LBP and found an Islands of Adventure/Universal Studios level. She found a fun level where the creator made the park exactly as it is set up. It was a great level.
Here I filmed the "Wizarding World of Harry Potter" section of the Islands of Adventure level. If you've been there, you can see it's quite accurate.
What a talented person! I'll need to find the user name who created this level.
