So what's wrong with that? I mean, obviously, from the company's POV, that's bad, since they want more attendance and therefore, more revenue.
But from my POV (and presumably that of every other visitor), I could care less if the addition of a new park increases attendance or not. If anything, I hope it doesn't increase attendance. Why would I want crowds to be any bigger than they already are?
But I also agree with others who have said that they would rather see improvements at the existing parks rather than the addition of a new park. There is still alot of room for expansion at AK, for example. My vote would be for another land there (Beastly Kingdom or Australia), rather than another half day park.
