Not a silly question at all. You would need to ride the monorail to the Ticket and Transportation Center. That is where you would switch to catch the monorail to Epcot. The Magic Kindom monorail goes in a "circle" and there are actaully two tracks. The inside track has stops at the Polynesian resort, the Grand Floridian resort, the Magic Kingdom, and the Contemporary resort. This one goes through the Ticket and Transportation Center, but I am not sure if it stops. The outside track takes the same route except it only stops at the Magic Kindom and the Ticket and Transportation Center. There is a seperate track, and monorail, that runs from the Ticket and Transportation Center to Epcot.
I hope this helps.
