Thanks to all who replied to my first post. It seems to be the consensus if parents pay for trip home then son sleeps at home...which is of course what we think and what we want. So the real issue is that we wish this is what he wanted. Now, for the next issue. Let's hypothetically say that son does not like to be confined by parent's rules because parents are paying, so next time he makes sure he has his own money and can pay his own way, would any of you be bothered that your son would be coming to "town" but not staying at "home?" So, this becomes more of a family values issue and not an economic one.
