Another idea to help imply the size of the camp would be to have half a bridge over the gap at the end of the board (so that the "missing" half of the bridge would be on the theoretical next board).
That gives you a link between the halves for gaming, implies a bigger camp, and takes up a minimum of space.
Between that and the lift, the area becomes a lot more playable (and after all, this IS for a game!

)
