Top of most children's bill was the Studio Tram Tour and the Rock 'N Roller Coaster which goes from 0 to 100km/h in just 2.8 second!

Children were also desperate to see Armageddon special effects where you become the actor in amazing effects based on the film.
People waited an hour in the queue, only for it to break down!
But the Studios seemed to have impressed most so far.
