A couple considerations:

Batteries. I would suggest that any team hosting such an event clean out the local supplies of FRC-legal batteries long enough in advance to charge them. Then all the attendees bring all their batteries and chargers. Any batteries the hosts don't want can be distributed to teams who need more after the event.

Quiet/Sleeping rooms or other arrangements. Some folks will want to sleep, at some point, and probably want someplace somewhat comfy to do it in. I'd suggest some rooms off to one side, out of the way, probably at least 4 (2 for adults, 2 for students, and separate male/female rooms for both age groups). This will also simplify some of the logistics for teams running rotations.

Would I personally be up for doing it? Possibly. But I do run out of awakeness after a couple dozen hours or less.
