I am debating whether to do this. Does it take place in both IOA and universal or just universal. What rides are open? If I go it would be on a saturday, 10/4, and I read that lines get very long. Would I be able to hit all the houses if I do get there at 6:30? Is it really worth the money. We have been to the haunted things at places like six flags new england and they are not really scary for us. Thanks for any info.
