Yes. Dad and I had to move out of the family section for the same reason. The rules are easily circumvented if you have a young relative that you claim comes with you even if they never do.
I could get some poor unsuspecting (?) girl pregnant, then get back into the family end with a ticket for the three month old child that wouldn't be going for the next few years at least. Similar methods occur with people using the details of nieces/nephews.
