> If you're a cruise line or a convention service, there's no market

Cruise lines are in a rough place. Same as airlines.

Lots of convention and vacation related businesses might face a more interesting dynamic. I briefly worked for one in college. Their fixed costs were probably less than $500/year and they kept low six figures in the bank (very high variable costs, mostly enterprise clients, and a fairly old-school owner).

Lots of small travel-related business can “survive” basically in perpetuity. But they will probably face a lot of new friction when events held at the convention center start running again. They can burn capital to stay alive and feed the owner in the mean time, but as that capital burns away, so does the business's feasibility (because of cash flow issues). Bankruptcy and business closure rates are going to vastly under-estimate the number of small business that de facto die out.
