Did you say College visitation?  Hmmm... Your baby is no longer a baby.  If he/she is old enought and big enough for college he/she can go by themselves or invite whomever to go with at that time (friend, parent, or no one).  Those whom are financially paying (especially if child support is being paid) are the only ones whom should have any kind of feedback and imput to the choice/decision besides the adult child.  If he or she is still receiving child - I mean, adult - support the student to be should sit down with both parties and have a mature discussion about college, major/field of study, expenses, responsibilities of student (financial - students who pay forthemselves get better grades in school) etc.  It is part of growing up.  If the adult child cant do this then he/she is not mature enough for college.  Step-Dad and Step-Mom need to stay out of it unless they are paying money out of their own pocket and have received a personal invitation from the adult child.
