Gypsy and MrsH hope your DD get better soon and are enjoying some TLC at home.
Voilets and Noits I think it depends on the course.
DD seems to have the opposite problem - plenty of friends on course, but not from halls. They get along OK but little in common and all keep very different hours. Probably not helped by being away most weekends so far.
She has joined subject society, so also made friends in higher years, but only between about 40 and 60 in each year.
Would definitely recommend joining the subject societies, or other societies that may attract from subject.
Noits that does sound disappointing, hope he gets to spend some time with his brother too. Would think the GFs family would have something to say too. Also would be inclined to withhold lifts.
Hope all those with DC home this w/e have a great time and DC get sent back recharged and raring to go.
