<p>fluffloooz, you can tell which rooms are singles and which are doubles by the new mailing. I just received a package today from Williams that lists everyone in my entry (Williams F, for the record) and which room they will live in, and so, if there are two people listed for a room, I assume that those rooms are doubles.</p>
<p>And if you do not get that mailing… well you’ll find out in four weeks anyways :-P</p>
