For example I was travelling to the Caribbean on holiday with my wife, three 20 something kids and their girlfriends and we have been allowed in, but the conversation at the desk started with my recognizing that I was pushing the limits, and I was told that yes I was but as the lounge was empty she would let us in.
Now my wife and I were probably in paid J, and my wife may have had E35 that year as well but still there were 5 others only three of whom were my "children".
As I have mentioned elsewhere my eldest at 27 will be SE this year so he can guest the rest in in future.
