>There's a demand for all sorts of consumer items in the world but people hit their limits.

That's the thing with a lot of VC-subsidized services. There are a lot of services that consumers would be happy to, well, consume if they were cheap enough. Drivers, personal chefs, weekly housekeepers, lawn services, laundry pickup, etc. Even people with an upper middle class income are pretty selective about that sort of thing.

>But many would rather go back to the tiny fridges filled with pricey junk food they never touch, if it means saving hundreds of dollars a weekend and flexible cancellation policies.

Kitchens are not a big deal for me when I travel. A fridge is nice but you get a small one you can use a lot of the time in hotels these days and minibars seem to have mostly gone out of fashion.
