Continuity mistake: In the scene where the boys are fighting in front of the "Avalanche" ride which Medusa has sped up, Amanda hits the emergency stop button and accidently stops the ride upside down. In the very next shot it shows one of the boys fighting in front of the ride, and the ride is now moving.
Revealing mistake: In all the scenes where Tum Tum kicks the ninjas, you can tell it is a fake leg in the closeups.
Revealing mistake: When the main villain (I can't remember her name) is about to press the buzzer in the theme park to get into the security section, or whatever it is, the buzzer starts buzzing at least a second before she presses it.
Audio problem: Right after Rocky jumps over the fence and kicks the ninja that is holding tum tum he says "give me five". But his lips don't move at all.
Revealing mistake: When the three henchmen head backstage to Paul Hogan and one shoots a sleeper dart at him, it's obvious he dosn't shoot anything. Also when his body is lying on the ground there is no dart in the body or around it.
Answer: No they don't, the rides are controlled individually by a ride operator at each ride. This was just made up for the movie.
