As an alternative, you can take the bus to the Disney-MGM Studios, then transfer to the Wilderness Lodge/Fort Wilderness bus. This will drop you off at the Settlement Depot at Fort Wilderness, near Pioneer Hall.
If you are attending one of the late Hoop De Doo shows, there will be several buses parked near the Settlement Depot that will take you directly back to your resort, without having to transfer...you might have to wait through a couple of stops on the way, however.
The same service is available for guests dining at the Rain Forest Cafe at Animal Kingdom. Buses continue to run for Rain Forest diners until everyone has gotten back to their resorts.
