I have a 6 man BPWD luna 6. We slept 4 side by side, 2 of those young kids and that was about all I wanted. Sides are 10' (Square tipi). That said We put 3 and a stove in it by sleeping around the perimeter. No room for gear though. 2 with gear with no stove (although we could have set it up) was about perfect. There isn't that much weight penalty for a slightly bigger tent.
