Please don't rely on the legacy to "ensure" admission. Remember that legacies typically only get a "boost" if they apply EA/ED. Stanford legacy does provide a boost - last I heard was legacy admit rate around 14%, non-legacy 7%.
Better chances if you are a recruited athlete with decent GPA and SAT. We can't rely on the athlete thing at a school like Stanford as mine are not DI material, but it can help at DIII schools. And other talents can help, such as music, art, etc.
My eldest passed up free tuition at a couple of decent schools (merit based on GPA & SAT). I'm hoping my youngest holds true to her word that she'll take up a free tuition offer at a local university if she has the scores.
