I have to say I am biased. I have only been to Disney World so of course it is my favorite. It is not to far mind you it is easier to take a plane, but out of all the Disney parks it is the closest. I also love that it is near the beach so if you do plan a trip with your family you can spend 3-4 days at Disney and then 3-4 days at the beach. Don't get me wrong I would love to visit the Disney parks in California or Europe or even their gorgeous Polynesian resort in Hawaii but practicality and a sense of comfort make Walt Disney World my personal favorite.
