There is a outdoor lot half way through the studio tour which has a few big sets from the movie. This is where I stopped to have my lunch and bought a glass of butter beer (for all the Australians it tastes like creaming soda). The second half of the studio tour is much more about the behind the scenes. There is a large section all about the creatures created for the movies as well as amazing works from he art department. Really the best part of the second section of the tour is the scale model of Hogswarts and the grounds. It is huge and you can walk all the way around it. The lighting also changes continuously so you can see what the castle looks like during the day and at night. Finally just before the gift shop is a room full of wand boxes which has the names of everyone involved in the films. Spend some time and see if you can find all the big names including J,K Rowling.
