I am glad to hear that Carsland will be coming to DHS. Like DCA, DHS could use a few more attractions and this will fit in great. Someone on another similar thread suggested they incorporate the Cars 2 locations. That could be an interesting way to make it unique. Anyway it will be a couple of years before it can be built so DCA will have it exclusively for quite a while.
I like to think of it as being similar to what happens with a chain restaurant or clothing store. When you walk into a location of a national chain restaurant you know about what you will get. Locations tailor things to meet the local tastes and local market of course. But Chilis chips & salsa is about the same in Denver, Houston, Philadelphia and Atlanta. When you have a great concept, expansion often follows.
