I camp with my family, my wife, an 8yr old and 14month old. We have a 6 person dome tent similar to the "breezeway family" but the front section is not floored and all 6 sleep in the main tent area.
The weight is a little more than the 7.5kg states in the breezeway, we find this tent is nice and roomy, not to squeezy and just right (as long stretcher beds aren't used). I would hate to down size into a 4 person.
i also have no real experience in the tent you are looking at, but my 2cents.... go with what you like.
a tent is a tent, if you all fit nicely in it, and it has the ventilation your after, why not.....
Choosing a tent in my mind is about room, rather than features, if i wanted features i'd be buying a CT
not sure if that helped you at all DaveM......
