I don't think it would be that hard to stay loyal for one week away.. If you really like the person you're with then you wouldn't even consider hooking up with someone else.. Me and my bf are going to separate schoolies destinations and both agree that cheating on schoolies is the same as cheating any other time.. I don't have a problem with him meeting new ppl and making new friends, thats part of the schoolies experience, but if you really care about someone u don't need to be hooking up with other ppl just to have a good time..
That's just my opinion tho...
