Heading abroad for a holiday and to visit family. Husband is not from UK and from place we are visiting. BIL wants to fly nephew across country to stay with us for 3 nights (BIL can't come) and then join us visiting other family for a few days. Nephew is 14 and doesn't know us. I'm slightly apprehensive. He doesn't come from a great background. This will give him a trip away, time with us and to meet our young kids. Would you do this...?
