This is a good size 5 man family tent. Realistically this is good for 2 adults and 2 children or 3 adults. You could put 4 adults in at a squeeze but I wouldn't fancy it myself.
Vango are a good mid range tent manufacturer and this is a 4000 HH waterproof fabric.
You wont do much better than this for a quality family tent.
