I see the Disney bubble a bit differenly than others do. I get MUCH more of an emersive feeling at DLR (staying at DLH) than I have at WDW (last stay Contemporary).
There's nothing more bubble bursting to me than a bus or a bus ride. I don't care that it's a Disney owned bus, it's still a big ugly stinky bus. Of course one could forgo the buses and drive their car from their hotel to the parks, but to me that also bursts the bubble. For me being able to walk out of of my hotel and stroll to the available parks, is what makes DLR a MUCH more emersive trip. To not have to drive or even see a car or a bus keeps the bubble intact for me.
As for the locals VS tourists breaking the bubble..... I don't know how anyone can tell the differance between most locals and tourists. If being able to pick out tourists is because they are wearing hidious matching t shirts,
crocs and look like they have no clue where they are going is how one can tell, I'll take a park full of locals over tourists any day of the week. However I will say that WDW gets a lot more people from outside the counrty and you can usually tell they are tourists when they speak. Let me tell ya if I never have to put up with the rudness and lack of knowledge of personal space we encountered with foreigners at WDW it will be soo soon. LOL
Another part of the Disney bubble to me is making the most of my vacation time. At DLR the vast majority of my time is devoted to enjoying the parks. At WDW too much of my time is devoted to just getting to the parks. That bubble starts to leak every time it takes more than a few minutes to get anywhere......
