The tour took us onto the actual Universal Studios lot. We saw actual soundstages that are actively being used to film shows and movies.
They also had a few attraction like areas for us to go through, like a 3-D King Kong adventure, a violent car chase from Fast and the Furious, and a pretty cool earthquake/water simulation in a subway station.
I had to hold onto Magnolia a few times on some of the scarier parts.
