What show are you going to?
If MK is still open, the bus to MK and boat to FW is the best option. When you get off the bus at MK, start walking towards MK. You will walk past the big ferry boat dock. You will then see the sign for WL FW boat. The boat will stop at WL first. With waiting for busses and boats, figure on a least 60-75 minutes to get there.
If you are going to one of the later shows, and MK is closed, there should be busses right at the settlement bus stop (near Pioneer Hall) to take you back to your resort.
