The bus service at All-Stars is tops! At Ft. Wilderness unless you have a golf cart or bicycles, it is a two-bus ride every time.
If you really want to spend time in the parks, All-Stars is the better choice. If relaxing, quiet and the great outdoors is your thing, then Ft. Wilderness is the better choice.
I seem to want to hang around the campground more and relax when I stay at Ft. Wilderness. When I stay at All-Stars, I am more motivated to get to the bus stop and "get out there".
Another consideration for All-Stars, the food court! It is so much easier to grab a quick, small breakfast on the way to the bus at All-Stars. Ft. Wilderness only has a full buffet for breakfast. But then you would be in a cabin and can keep your own quick breakfast stuff.
One more point for All-Stars, when requesting connecting rooms, you can request that one of the rooms be handicapped equipped, then you get a King Bed for mom & dad, with a fridge, while the kiddos can share the connecting room with two doubles.
Hope I've helped!
