You Be The Judge: The Family Vacation Dilemma

Andrew from La Jolla has a "Dad Dilemma!" He is taking his family on their yearly summer vacation and his 20 year old daughter is taking a boyfriend...and Andrew is not particularly fond of the boyfriend. She's taking him along because they've always been allowed to "take a friend" on vacation. Does Andrew allow this to happen? Or walk back n his promise that the kids can take a friend on the trip?
