Disney Answer: Yes and No!
No – Walt Disney World’s Magic Kingdom and Epcot are actually about 4 miles apart. Walt Disney World is huge, about twice the size of the island of Manhattan, and everything is really spread out.
Yes – In a way, the Magic Kingdom and Epcot are connected, by monorail! You can ride from Epcot directly to the Magic Kingdom (with a change at the Ticket and Transportation Center) by monorail. The one-way monorail trip takes between 30 – 40 minutes depending upon wait times.
To see how far apart the Magic Kingdom and Epcot are, as well as the monorail route, check out the image below.
I thought transportation was free around WDW.
@Rhonda – All Disney transportation on property is free. Did I mention in this answer that there is a cost? I don’t see anything, maybe I missed it.
