5-6 hour continuous shoot?

I am photographing (WAIT, hold on) an event in a few weeks and my client asked if there was a way to film the dance floor for the duration of the event to grab the highlights. He doesn’t want a second shooter as I’ll have to increase my rate.

Is this possible? And if so how can I pull it off?

I have an a7iii, a7siii, canon t5i and theta 360 cam at my disposal. My client also works in the security camera space and told me he has access to a bunch of cameras if need be… He told me it doesn’t need to be anything too high of quality but just something to be able to look back on.

TIA!
