I actually think it was WRONG for the parents to GIVE him a cruise, and then say, "You just can't take our daughter with you." That seems like a major set up, or something else is on the parents mind to do that to both him and the daughter. We also do not know why the daughter is still at home, what the parents stand is on other things (i.e. curfews, dates, etc...) and there are several other reasons that might spark their problems with her and going on vacation. I think that there is more to this situation than the daughter let on.
