To take a kid/skid on vacation?  I was reading a thread in the forums regarding skids going on vacation with parents/step-parents and it got me thinking.  Is there an age when a skid should be expected to plan/pay for their own vacations?  Are certain types of vacations appropriate/not appropriate for a skid to be taken for vacation (ie, lake house vs. Caribbean beach resort).  Should skids be expected to pay their own way?  Or pay for their own meals/entertainment?
