The campfire is at the Meadows area. Pioneer Hall and Trail's End Buffet are at the Settlement area. After the 7:00 and 9:30 Hoop De Doo show, there are buses at Settlement that go directly to the resorts rather than make people go to MK. If you can find out the times that those buses will be there, then you can time yourself to jump on one of them. You would have to take a bus from Meadows to Settlement, then wait at that bus stop.
If you have time to kill, there's a trading post to shop, Crockett's taven for a drink, some little kiosks to shop at, a small playground and the beach.
