Hi Plano,
Parasites are not bad. Or odd. They generally feed off their host w/o harming their host. A predator would have other intentions. It just means that the general Orlando attractions and tourist industry exist
because Disney World draws the tourists. If it's hard to think of Universal that way, then maybe think of... The Holiday Inn across the street. Or SeaWorld. Or Wet'n'Wild. Or
Legoland. All these smaller places feed off of Disney bringing customers. None of them would exist (Universal included) if Disney had not transformed central Florida into a tourist destination where 50 million people visit yearly. I've been to SeaWorld. And W&W. And Legoland. All on Disney trips. I would not make a trek to Orlando to go to an aquarium, I have one in my home town. But I would go to it if I was otherwise going to WDW and looking for a little something else to do on an extra day.
The Orlando area really only has about 2 million residents. That's not enough of a population base to sustain 5 theme parks (Uni, Ioa, Sea, Busch,
Lego) on their own. Much larger cities (Saint Louis, Dallas, Chicago, etc) can only support a single Six Flags off their local population base. These parasite parks
rely on Disney World bringing tourists to the area for their livelihood.
Around 25-times the Central Florida population comes to the region yearly, because of WDW. That's such a vast disproportion of visitors to locals.
Universal does a good job of differentiating themselves, and I have to hand it to them, for the first time a local park has come up w a strong draw of its own, in the HP theme. But prior to that, Universal was just a coaster park and was in a really dark age of 5 million guests per year. They've finally built some resorts... To become a destination of their own, they would have to attack the family market of parents with children ages 3-9. This is the core tourist market that chooses where to stay on vacation. And Disney owns that.
Universal does not
need to attack this, or be a destination of their own. They can focus on attractions for a little different market. Go after those 10-15 crowds. Let Disney bring the families, and then entice them to come to Uni for a couple days for something different. That is a parasite park, and it is a very good model.
