You can have seating for 1 to 16 people, including the pilot, depending on the occupants' and baggage weight. But the more luxury and creature comforts you opt for, then the more those things use up your available load weight, and the more volume they use up inside the cabin. Don't forget that peeps usually bring stuffs. So consider how much room their gear will occupy and how heavy it will all be. While the Grand Caravan is a true bruiser of utility Gen Av planes, load and space are still finite things.
