Again you say that they "easily" could of built it in the red or blue circled area, but you are just assuming. Logistically there could be hundreds of reasons as to whey they couldn't, electrical, plumbing, existing infrastructure, being able to get equipment in and out, while keeping the park open, guest safety, etc. There are so many factors that go into a major project like this and you just keep minimizing it like its easy peasy, just plop it anywhere. You clearly don't have the experience of a major project like this, try to look at it from a different prospective please.
