The queue for Legacy of Olympus enters through a museum of Roman art.  Classic Roman art (such as the ones pictured above) are restored in this museum.  When one walks through the museum, signs advertise for a Roman Countryside Tour.

Two years after the attractions opening, Disney added a separate line for guests who just wish to walk through the museum.

 

At the back of the museum, an audio-animatronic attendant states, "Oh congratulations! You're museum ticket got upgraded to include the tour.  The tour boards in the Historic Ruins just a bit of a walk outside this door. "  Guests exit the museum, and take a short walk, up a hill to the museum, where they board their vehicles.
