I've only been to the US parks. Disneyland as a very small baby according to my parents but I don't remember a thing! And Disney World, well, five times if I recall.
I'm not really interested in the international parks. I've already visited Hong Kong and Shanghai before they built their Disney parks so there's not really an incentive to go back there. I have to really love a place in order to go back. Never been to Tokyo but I'm not really crazy about Japan. Love Japanese food but I can't see myself going to Japan. The distance and the language barrier worries me and being that I'm Asian-American, I feel there are higher expectations from me to speak Asian languages fluently! As for Paris, well, Disneyland Paris isn't really an interest of mine. The rudeness of the park guests, CMs and the whole in-park environment worries me and I've heard how appalling some parts of the park look, at least, from an aesthetic point of view.
Really want to visit Disneyland out in California. I've never been to California Adventure and from what I've heard, it's not as touristy as Disney World.
As for my favorite park in WDW, it's the Magic Kingdom. The most rides, the most characters and it's the iconic Disney theme park.
