No idea about family type camping, just lightweight hiking nerd shit that costs more money than is sensible. My sister and family unit (inc 2 kids) have a Bell Tent which she loves but no idea on how that compares price wise to other types.
I’ve been involved in a wide range of camping disasters, typically involving wind, rain or fire. None really interesting enough to extend beyond ‘things blew down/got soaked/burnt’ so I won’t bore you with further detail.
