Typical stretch limo arrangements can be found below for your reference.
A 4 to 6 passenger stretch limo sedan typically has two bench rows facing each other and offers ample leg room. Some versions of this limo, however, have a J configuration, with the back seat in its traditional position and a bench row along the length of the stretch limo for additional seating. (Check out the interior of this classic stretch limo!)
When stretch limos are longer, such as a 12 passenger stretch limo or an 18 passenger stretch limo, the seating arrangements tend to alternate so that some parts of bench seats face each other while other parts of the bench seats face a bar or two, depending upon the length of the stretch limo. The back seating area in these stretches can be traditional, but more often than not they are designed with classier seating and commonly referred to as the Bride and Groom seating area of the stretch limo.
