Orlando is the location that most folks think of when they think DISNEY. But actually WDW is located in Lake Buena Vista.
Walt Disney World and the other theme parks are NOT really that close to Miami. It is almost 250 miles and takes more than four hours to drive up the road. The beginning of the Keys is closer.
I do not think that Disney is a Must -See location either. But since some folks do, I'm putting it here.
THE SPACE MOUNTAIN
My favourite attraction in Magic Kingdom was a Dark Roller Coaster in which you can't see anything as the wagons go up and down at a really high speed. It's amazing, a real experience!!
THE LAKE AT EPCOT
Around the main lake of Epcot they have built the main touristic places of the world (Eiffel Tower, a mexican pyramid, San Marco Tower, a chinese pagoda...) so you can take walk around the world here in about 1 hour.
There are also typical restaurants and shows from each of the countries represented here, a nice evening!!
