I had an "in office" role in Birmingham last summer requiring a hotel stay while onsite, 5 mins walk from the office.

7.5 hours done, back to hotel for job 2 (It was a global project, time was flexible). Deliveroo and 7.5 hrs done there, ablutions, sleep, repeat.

Double billing *WAY* better than isolation in a hotel room / going out drinking / eating out etc 5 days a week.

But your YMMV...
