You'd be better in the Family Stand bud. Which should have a third tier in a few years?
As for pricing, its separate SC's however pricing is variable based on age and seat location (which is why I recommend the family stand)
For your lads (who qualify for junior blues)
I've took family into the family stand and to be honest the kids didn't like it as they preferred the atmosphere and standing in my regular block (kippax corner)
So your boys may like/dislike the family stand.
