It is important to note that in a "regular" year, the people housed in the Westin Copley would not have even been housed on the Boston campus for their first semester. The entire cohort of students living at the Westin were all from the NUin program, which typically has these students taking their courses abroad at various international universities that NEU partners with.Not to derail the conversation from housing stock too much, but I was actually one of these students who graduated HS in 2020. I'm under the impression that fairly few students chose to delay enrolling for a year, and in fact, most chose to live on campus. It certainly felt like I was in the minority when I chose to take classes remotely the first semester.
My guess as to why this is the case is that while Northeastern likes to tout its financial aid, I think a substantial percentage of the demographic remains the type of people who are more unfazed by a steep charge for virtual classes. As for the current situation on campus, housing stock definitely remains at or above capacity. I personally know many people who were stuck in the Midtown Hotel as mentioned above or even the Westin Copley. Some people attribute this to COVID density restrictions, but as far as I know, nobody is being placed in a single when they otherwise would have been placed in a double unless they have actually contracted COVID.
With regards to the Midtown Hotel, NEU usually (in a "regular" year) only occupies half of that building for housing purposes. The only reason they occupy the whole building this year is because NEU decided not to have any triples (or larger) bedrooms this year due to social distancing limitations.
