But the fact remains both parks are accessible to most of the US. Sure it's going to be a longer journey to cross the country if you're a CA or FL resident, but the costs aren't even remotely comparable to international travel.
Leaving Cars Land as a DL exclusive means they will always draw SOME additional business from customers wanting to see the uniqueness of that resort. The more homogenized WDW and DL become, the less incentive customers have to make those extra visits.
And really the only benefit to Disney is saving on development costs. As a consumer, that's a pretty crappy justification for constantly replicating attractions at both Resorts.
If WDW is drawn to the appeal of the Cars theme and merchandising potential, by all means add some Cars content to Florida. But make it UNIQUE. Copying their work from the other side of the country smacks of cheapness.
Speaking as someone who has made annual trips from the midwest to
Disneyland for 4-5 years now, the lack of innovation at WDW has absolutely cost them some of my money. I rode the Little Mermaid attraction at California Adventure 1.5 years before it opened at WDW. That MK addition was meaningless. And if they can't find any other way to spend $800 million in Florida other than to replicate Cars Land, they'll lose even more of my money.
Give us Star Wars or something else unique at WDW. Give me a reason to spend more time there. Right now, when I want my fill of Space Mountain, Star Tours, Tower of Terror, Soarin or dozens of other attractions, I'll choose Disneyland over WDW every time.
