How do I expense my business cruise event?

rebelman1 · ‎September 19, 2020

I'm a solo business coach and Sch C filer. I am hosting a multiday business cruise for my business clients and their families. I'll conduct at least 4 hours/day of business workshops on most days of this cruise.
The big question-
I'll pay for my cruise, but how do I expense my business cruise event?
The participants will pay for their cruise, but how do my participants expense their business cruise event on their Sch C?
