We stayed at the Ft. Wilderness Cabins last year. (bolding because there is no such thing as Ft. Wilderness Lodge, which is confusing to people because you never know if people are talking about the cabins/campground or the lodge.)
Bus transportation to the races was super easy and probably even a little less hassle than at some of the other resorts.
The internal busses started plenty early in the morning, and take the runners to the Outpost, where there pretty much always seemed to be a charter bus ready to get to the race, with shorter lines than we've seen at other resorts in recent years.
We didn't have a golf cart, but were in a cabin towards the 'street end' of our loop, so the walk to the bus was not long at all.
