Our family of four-2 adults and 2 teens- can sit comfortably at our
Scamp dinette, same size. For lounging we prefer to spread out more- 2 at the dinette and 2 on the front sofa, but for eating a meal or playing a card game, no problem.
I assume if you're eating inside, it's probably too cold/wet/windy to cook and eat outside, as that's the logical place for a dinner party. In which case, the real challenge is preparing food for a crowd on the tiny galley in that layout!
I agree it's an unusual thing to draw attention to as a selling point on a trailer that's really designed for a couple.
BTW- to avoid confusion, it's best to post this in the "Referrals" section of the Marketplace.
