The problem with voting which park is the best is that it is all based on bias. I am willing to bet that almost no one in this post has been to CP, PKI, MM, SFGA, Disney, IOA, SFO, Kennywood.....etc. My point is, You can only say what park is the best only when you have been to all the major parks in the United States and around the world. Japan and the UK have some outstanding Parks(Alton Towers and Blackpool Pleasure Beach). Personally, I say CP is the best, but I don't know for sure. There are only a select group of people that have been to all of them, which gives them the right to say which park is the best. And even then, their decision is still biased because what one person may like, another does not. Just my 2 cents.
