in my opinion, the worst park is the "luna-park", in alanya, turkye!
they have a swing ride that has no restraints and the restraints in the pirate ship open while operating....
i think, it´s the best park to get rid of your mother in law, if you want to, just invite her for a ride on one of these death machines....
p.s.: i love my mother in law, she´s a wonderful person!
