Sounds like a business opt for someone. Round up a few used
mobile structures, trailers/campers, move them in and let the
people stay there for a few months and close ‘em down when gone.
Open ‘em up next year when the visitors began showing up.
I thought of that, and I’m sure the business owners have also. I’d guessing there are levels of bureaucracy standing in the way.
Not a terribly bad idea. There used to be employers that provided housing for their employees, and some of those housing units still exist (often as more of a museum piece than anything). Look up the history of the Austin Powder Company in Glenwillow, Ohio, where a row of "company" homes still exists, but not as company homes..
Personally, I've considered buying a modest trailer, living in it for a couple of years, and selling my house while the market is insane, then buying another when the market takes its inevitable dive. But that is actually a good amount of work, and I've noticed that trailers and RVs are through the roof expensive as are houses now days.
