Regarding singles, I believe some schools felt they were important if there were going to be a large portion of courses taken online, so that students would have a private, quiet study space from which to Zoom. I don’t think those decisions revolved 100% around covid spread, but also for class work. As more of those schools get more comfortable opening up other indoor spaces beyond libraries to work in (empty classrooms, etc), having singles may appear less important 2nd semester.
But of course, covid-spread was part of the rationale. What I think will convince schools that they can go back to multiple occupants per room will be seeing what happens at other schools this semester. In Boston, Northeastern, Tufts, and BU all test all students 2x per week, and invited 100% of students back. Harvard and MIT testing 3x per week, but invited just over 25% back for 1st semester. BC not doing mandatory testing of all students, invited 100% back. Berkelee, Simmons, all remote. The only one of those schools that has experienced an outbreak so far is BC—the one without mandatory universal testing. If NEU, Tufts and BU can wrap up the semester as successfully as it has begun, then I think it becomes harder to justify the “singles only” policy at other campuses. They will prove that doubles (paired with frequent testing) work fine.
Regarding life on campus, my freshman is very, very happy to be on campus. Aside from nice suite mates, DC has made lots of friends and is very busy. Masks are annoying to all of us (but worth it), but they are used to it and can make friends anyway. My child’s campus has had zero undergraduate cases for at least two weeks now (although 6 cases among staff/faculty in past 7 days). Each campus is different, but they all have outdoor spaces and plenty of opportunities to do stuff. Kids are coming up with new things that they didn’t used to do (way more ideas like corn hole tournaments, new outdoor spaces are becoming “hot spots” to gather, more eating out in outdoor restaurants as Friday night activity, apple picking, kayaking, etc. They are not necessarily having the exact same experiences as are typical, but they are finding things to do. I’m sure there’s also little bits of rule-breaking that goes unnoticed, too, and on campuses with frequent mandatory testing and no/very few active cases, that probably isn’t quite as risky as it sounds.). The fact that schools are wrapping up in late November means that outdoors with proper clothing will probably be doable for the vast majority of colleges for socializing. Weather has been ridiculously accommodating in the Northeast for outdoor socializing (the flip side of unfortunate drought conditions is no rain forcing kids indoors). I do think there are fewer 3 am or 4 am nights out though, which may not be a bad thing!!! My kiddo will certainly enjoy next year when hopefully things like tailgates and regular parties and full in person classes and In-person activities and theater and sports, etc are back, but this year is far from a bust so far. Just like all of us, the students are making the best of their circumstances.
