Using legacy choice for residential college?

<p>My son has the option to choose Silliman, but is wondering about giving up the old campus experience. Any thoughts on this from current Yale students? Also, if he doesn't use his legacy option, will he enter the draw on different terms than students who should just have a 1/12 chance of being placed anywhere? This policy doesn't seem fair to all, but since it exists, I am wondering how it works for a student who does not use his choice option. Thanks.</p>
