My favorite is MGM/Hollywood Studios. I looove movies, and the "old hollywood" feel of the park.
Plus, it has my 2 favorite rides, Tower of Terror and Rock n Roller Coaster.
Either the Magic Kingdom or Epcot. (I have never been to Disneyland before). I love Epcot - it has so many different things, and I love looking at the different countries. The Magic Kingdom is just so Disney to me.
For me? Magic Kingdom, definitely. To me, it feels like its the park that contains the most magic. It's the one that is more suited to the younger people and its main focus is the 'magic' of Disney. Magic Kingdom and the Castle is the first thing people usually think of (well i don anyways) when Disney world is mentioned
