At Christmastime anyway, we were sometimes able to tell the driver that comes to pick up people where the employees catch a bus (can't remember what other lots/destinations that bus serves--but it's way on down from the turnstiles) that we were staying at Deer Run, and the driver would take us there. On our visits, it's been a Silver Dollar City bus that picked us up and brought us back to Deer Run. Deer Run has a schedule, but sometimes they will return you to Deer Run off-schedule if they can. It can't hurt to ask.
Otherwise, we get off at the tram stop (is it 5? 6?) that is on the same side of the highway as Deer Run. It is a steep walk down to the motel, but not too bad. It's a rare day (at least on the weekend), that no one is parked in that lot after a few hours of being open.
This has been are experience for staying at Deer Run for our last three Christmas trips.
