Universal Studios! Not as much to see as the one in Florida, but Shrek 3-D just opened there!
And if you want, try to get tickets to a filming of a show you like. Its pretty easy to get into the Tonight Show...just pop in the studio ticket counter and ask for free tickets. Somedays the tickets go out faster than others...and some nights there isn't even a full house, like when we went last year (I guess no one was all that hyped about seeing Dr. Phil...I WAS THOUGH! lol). If you look on the internet, you can find what shows might be filmed during your stay and order tickets...I think they are free.
