The easiest way to get to Fellowship Hall is to go in the Main Entrance. Turn in from Pot Spring Road and park in front of the entrance. If the door is locked, ring the buzzer on the right to be admitted. Turn left inside the door, go through the double doors, then you have just a few steps before you turn right to go through the doors to Fellowship Hall.
The elevator and stairs to the sanctuary are on the other end of the hall, past the stage.
