Geodesic tent masters Heimplanet* have released their 4- to 6-person tunneled NIAS so you can pack in the whole familia without sacrificing privacy, or go camping with a big lot of crap and keep it all covered and close while you sleep. Like Heimplanet's Cave tent the NIAS builds on an airframe, an inflatable base that requires no assembly, and swells up into a sturdy structure straight from math class.
Use the NIAS' 2-cabin design to separate the girls from the boys, or the men from the boys, or the snorers from everyone else. If you don't need the second 2- to 3-person sleeping space, remove one to create a vestibule for equipment safekeeping.
The tent has an entrance on both sides, each leading into a protected area, and the connection between the two facing cabins. It covers about 107 square feet of ground, with an overall height of 60", and interior max height of 45". Pack size is 24" x 12" x 10".
