They have made noises about doing this but didn’t follow through. I had a season ticket in 232 from 2013-14 and they never said anything about family groups at that stage.
The guy who sat next to me had a six year old son and they relocated to the South Stand tier three when it opened because the seats were much cheaper there. Someone behind me was threatened with relocation because his children were over age. He, and his family, still there now!
The whole administration of the family stand is confused, and at times self-contradictory. The area is far too large to be sustainable as a family stand, hence all the anomalies.
I remain convinced that the empty seats are pretty well all no shows by season ticket holders rather than unsold seats. The seat next to me is occupied at best for two thirds of League matches and it has always been sold as a season ticket and is never available for purchase apart from Cup matches. It has been much the same for the last seven seasons.
There are a few blocks of seats in the lower tier which are sometimes occupied by visiting groups often dressed in the same kit (junior teams?). I suspect that these are the seats that may be given as comps for a few games.
There is absolutely no prospect of major changes in the Family Stand. It would be far too disruptive. Maybe, when or rather if, the North Stand is expanded there might be major relocations.
