Over 6 million of us enjoy visiting theme parks every year. With thrills and spills, you can make memories to last a lifetime.

Highlights include the magical Disney parade which turned into a nightmare when the famous fire-breathing dragon became an inferno in front of shocked onlookers. A catapult ride fails to get off the ground and we hear of one man’s close call on the day tragedy struck the Smiler Ride.
