I really don't see how they can ever add a third park. Does anyone have an aerial view of Disneyland? Honestly, there is no space at all. Disney World is where the space is at and maybe if Walt bought as much land for Disneyland as he did for WDW then there wouldn't be a question at all. I just can't see where there is room for a new park. As for Disneyland itself, well, there are a few pockets of space to add something new but not a whole lot. This doesn't mean Disney should ever rest on its laurels, I just don't think the park is going to get any bigger.
