My two cents. Advice itself isn't right or wrong. It's someone's opinion, which would make it good or bad. I think in this case she gave bad advice. She really took the easy way out instead of providing a more detailed response. Although we don't know all the facts surrounding the situation, I think this girl should go on the cruise. Just because she is going on the cruise with her boyfriend, doesn't mean that they are going to play headboard hockey the whole time. The parents seem to show a lack of distrust if they feel otherwise.
Fortune favors the bold.
