UPDATE – OCTOBER 25, 2009 : SAFETY CONCERNS
Due to safety concerns for the public and space limitations of our facilities, the halloween party has been cancelled, there will be no special events for halloween night. The haunted house will operate as normal. We apologize for the inconvenience.
In an effort to spread out the crowds during our final week, we will be open to the public for one extra week (until november 8, 2009), those who did not get a chance to see shanghai nightmare are encouraged to come visit after halloween.
