Tartan Tigger has the right idea - the best way to get to Fort Wilderness from the All Stars is to take the bus to the MK and jump on the boat to Fort Wilderness. You can do both the hayride and the campfire in the same day if you time it right. The hayrides are at 7:00 and 9:30 PM nightly, weather permitting, and the campfire is at dusk, I believe. Depending on the time of year you are going, the MK may be closed by the time you are finished at Fort Wilderness. If that is the case you will have to take a bus to Downtown Disney and transfer to a bus to the All Stars from there.
