I also have the usual concerns about hedonistic lifestyle etc
You need to let him go! 
The university I work at is planning - as far as we can given this appalling government's lack of planning - for the return to campus in September to be as much like the before-times as possible. Large lectures are likely to be online (my students certainly seem to prefer that than 9am in a cold lecture theatre!) but seminars, workshops, labs & tutorials will - we hope - be face to face.
If you're concerned about lockdowns, you might ask the University Residence team about whether they're organising freshers into bubbles. This will mean that groups of them can stay socialising, even if there are restrictions or a lockdown.
Again, at my place, students in halls were annoyingly and illegally incorrigible about creating social events. A couple of times, police had to be called, they were being so social! C-19 travelled through the student population via the halls of residence - incidences in Sept 2020 in my quiet country town multiplied ten times in October 2020. My university had to do a lot of PR work with the town & liaison with Public Health to reassure the local authority that C-19 was not being spread beyond the campus ...
Long story short: even through restrictions September to December 2020, and lockdown from January 21, students at my place seemed to enjoy themselves! Certainly when restrictions eased last month, the town centre was pretty much back to normal on a Saturday night!
