In our school, boarders are not allowed off campus during the week, when normally they would be for extra curriculars, appointments or to go to local shops or friends houses. And they are welcome to go home any weekend, but facilitated if they want to stay on - so far more are staying weekends, and boarding houses will be open over mid-terms etc which is not normal (there are a number of international students who don't have another base to go to in this country for that break), and may possibly be open over Christmas.
Each year in boarding is a pod, so 1st years study in 1 hall, 2nd years in another room etc. Junior boarding house has massively cut capacity - 2 girls in what's normally a 4 bed room, and no bunks in any room. Senior boarding house has been completely filled (single rooms) and occupants study in their rooms entirely this year. Previously all boarders could study in 1 hall, and seniors could choose hall or own room. And to make best use of senior house, the 3rd years (junior exam year) are also in there this year (normally you move junior to senior in 5th year, so 2 years early).
Boarders go back to boarding house for morning break when it used to be whole school in main hub in school. Lunch is now split to odd years (1st, 3rd and 5th years) early and even years (2nd, 4th and 6th) on later lunch, and boarders eat in boarding house. For evening supper (far fewer - boarders and those day girls who stay on for evening study), boarders have always ate before day girls so that is unchanged but stricter.
But boarders are in their normal classes, doing PE, and can mingle with their entire class/year bubble outdoors on breaks.
School started with just trying to make school and normal life work, with sports and evening study both starting week 2 (normal gap). But other groups have been slower to get going - Model UN and eco club started this week (4), music teacher had taken time to work on procedures and sent out invite on Friday last (2 weeks later than usual), no lego club (coding and robotics) as cannot SD, etc. But it has been with a positive attitude to trying to make it work and not overloading everyone at once that they've been starting back.
And Headmaster was very positive in email to all parents last week about how the girls have adapted to new systems, getting on with everything, and how quickly "normal" life (sports, academics etc) have all got going again - even class bonding trips can't happen as they normally would (school has a very strong sense of community and family and building relationships, not just strong academically) but DD's class have been on a long walk to the local town to walk the pier and have icecream cones so they have escaped the classroom (including the boarders) - all wearing their masks.
