Take the South exit from the airport. It says DISNEY then I believe it's exit 6 again there are signs (it will say Magic Kingdom), you will have to pay 3 tolls-2 $1 and then .75 Once on property follow the signs to Magic Kingdom. Once you get to the toll booth at MK get into the far right lane and tell the cashier that you are checking into WL. Follow through toll booth and at the light make a right.
Enjoy! WL is a lovely resort
