I just had an idea:
Disney can only expand the "Disneyland" concept so far, that is to x number of locations around the world, before diluting its status as a "destination" resort. So how can they continue to expand their theme park business?
I say, by going regional. No, not by building complete "DL"-like parks on a regional basis, that would make no sense at all. Rather, by taking companies like Cedar Fair and Six Flags head-on in the "local theme park" business.
If Disney designed parks around the idea of a $25/head admission price, and built those in parts of the country currently not near one of their destination resorts, they would create a whole new level of business which they could grow continuously for some time (assuming the concept worked), because regional parks, being less expensive, can be built more frequently, and do not require the same "draw" that their destination resorts to do turn a profit.
In addition to that, they could take different concepts, ones not tried before - much like they do in designing the "half-day" parks for the destination resorts.
For example, their first regional park could be, say, somewhere in the Great Lakes area, and be "Pixarland", with entirely Pixar-inspired themeing. They could get away with doing things on a lesser scale, because with the parks costing half the price in admission and a clear-cut regional concept, people will expect only that their "regional park" expectations will be exceeded, not that they are receiving the next "Disneyland". In fact a whole marketing campaign around the idea that Disney wants to build parks which are more "accessible" to families could push this idea with a positive spin.
This would also reinforce the idea of the destination resorts as being "premium" experiences. Certainly Disney already sees them as such, but this will provide an "equivalent" (Disney-owned) comparison to further cement that idea in the eyes of consumers.
It wouldn't be Disneyland, but with the Disney touch upgrading the basic regional park concept, it would still be "Disney" without the expectation of being "Disneyland".
Example? For $25 admission, DCA would be a great park. Yes, even with the Dino shack, the exposed-track roller coaster, and the Six Flag-like queue areas. In fact, DCA, with more attractions and perhaps slightly less placemaking (but certainly some) would be a perfect example for a regional park. Only, of course, give it a stronger theme to go on.
