ET phone home... Back to 1985!... I think we have some dueling dragons to fight off...
NONE of these proved to be the threat that that masses thought. These were all anticipated attractions that were to be the death to WDW. Simple fact is this- anyone making the trip to Universal is doing so with the intention of spending time at WDW also, but not vice versa. My hundreds of trips to Orlando, I have never set foot in any Universal park, and those that know me, I purposely drive so I have my car/SUV at the ready... and never once have I had the urge to visit Universal. I will admit however, that on my next trip, I will spend 1 day at Universal, if for no other reason than to take a trip to Springfield! But nothing that Universal can do will spell doom for WDW. If WDW were to cease all operations, Seaworld, Universal, the town of Kissimmee, heck, even MCO would all deteriorate within months from vacancies, lack of gate admissions, and Orlando will again turn into the sleepy swampland that it once was. These other theme parks, attractions, shopping venues all really do owe their existance to the massive 40,000 acres to the west that once was home to a radio geek and some gators, but now has mouse. Nothing that these other attractions/parks come up with will draw any money from WDW. Simply put, Universal is able to spend that money to design Potterville because Disney had interest in it for the price that Rowling wanted. Why? They have enough income at the parks without spending all that money to bring people in. Disney has their own properties; they have no need to license someone else's property to boost attendance. Even in this economy, WDW seems to be at 80% capacity (gate, hotel, etc...), which in theme park standards, is unheard of! Not even the regional Six Flags parks reach capacity levels of the height outside of the traditional peak days- Memorial Day, Independence Day, Labor Day... WDW is far from bare, and in fact have parks at capacity on a daily basis. Pottermania was a week long anamoly. Let's evaluate the Universal attendance counts on the off-peak times and compare them to WDW's, and then we can have the argument ended once and for all- Potterville was not worth the money that WDW would have had to pour in, but it is a short term gain for Universal.
