The fact is Universal just could not beat the compatition. Just think about it Universal had just 5 haunted houses and two shows last year and just one thrill ride in Jurassic Park and the simulated thrills of back to the future. Now think about this Knotts Scary Farm last year had 11 haunted houses, two haunted attractions (a log flume, and a water rapid ride) and 4 shows, one stared Elvira the other was the Hanging that is like Bill and Ted and stared the Crypt Keeper. Plus Knotts has all of those rollar coasters including a top ten coaster in Ghost Rider. Then South from there you got Magic Mountain with like 12 coasters and 7 haunted houses.
This is why Universal could not compete. There just is not as much to do at Universal as there is to do at those two places. At Halloween people want to scream, and Rollar coasters make people scream.
This formula has Universal Orlando scared too, because Busch Gardens Howl-O-Scream could begin to rule Florida October nights in 4 years. Last year Howl-O-Scream Sucked, but they are learning from there mistakes and will get better with time. This years event will have much more to do then last years. So if Busch Gardens starts getting it right, Universal might have to switch there event from Universal to IOA to satisfy the younger scream audience.
