Yes. Although I’m not familiar with any monasteries that have policies about families coming to visit monasteries. In Buddhist countries most families know their role in the system and understood what they were relinquishing when the allowed their child to go forth. In western countries people rarely ordain close by to their family.
And in all cases families are busy with lay life and can’t visit often.
All that to say, any problems that would arise from families visiting are probably highly individual and policies wouldn’t be needed.
