And once you're in that rental car, exit the airport onto Lake Mary Boulevard. It is less than three miles to the intersection with Route 417. Get onto Route 417 heading south to Orlando (parts of this route require payment of tolls). Go about 40 miles to exit 6 (International Drive, Route 536). At the end of the ramp go straight. At the next set of lights go straight staying on Route 536. You'll go past the Marriott World Center complex on the right and the Nickolodeon Hotel on the left, under I-4 and onto Disney property. Once there you'll see all sorts of Disney directional signage.
