My 9yr old son and I use to love this place. Until yesterday when a new ride ironically called the Fun Twister malfunctioned while he was riding it by himself. By the way, the ride was closed just a week ago for some reason. As the ride reached the peak with him upside down facing the pavement 30ft below him it stopped. The attendant who wasn't paying attention didn't notice til my son and I yelled at him. He then seemed at a loss of what to do. I myself had to grab two park employees standing only 20ft away one of which was the manager. Both of whom showed no sense of urgency to get over to the ride and the one employee walked over with a smile on his face as if it was amusing. I immediately let him hear it. It took them about 5-10mins to get the ride to work and get him down. When he got down my son was an emotional wreck. Hyperventilating, crying and shaking. The manager offered no medical assistance, he did however offer a free ice cream cone! Which only upset me more, I told him he could give me my money back since we were only there for about an hr., first 45mins were spent spending more money on arcade games. I literally had to argue with him for my money back. It took another hr+ for my son to calm down, stop shaking and crying. He never wants to go on another ride again now and when we drove by there today he got emotional and scared from just seeing the place. Thanks "Fun"Plex
