<p>Welch is 24-hour quiet, as opposed to other on-campus dorms which are nominally quiet from 10pm to 8am. Said quiet hours are rarely enforced in most dorms; I'm not sure how well they're enforced in Welch.</p>
<p>Henderson is the substance free one. Residents have to do some form of wellness program; I have no idea about the details and I'm too lazy to find out. They also, of course, have to swear off alcohol and drugs.</p>
<p>Both of these dorms seem to be quite popular; they filled up pretty fast during the room selection process.</p>
<p>My S was in Henderson frosh year and liked it. It was remodeled that year. The only reason he moved from there soph year was that he wanted a single and couldn't get one in Henderson because his room draw number was too high. He has been in London Terrace and Scobell since.</p>
