I assume that area hotels are completely booked up, as they aren't really going to be there in numbers sufficient to deal with a large number of evacuees. Hmm. I guess that this is probably a common problem in disasters. And you don't want to have lots of liveable properties just sitting there idle most of the time, as it'd be expensive.
Hmm.
I wonder if it'd make sense to have some kind of "mobile hotel" service that uses RV-style trailers or something? Like, when there's some kind of event that produces massive demand for hotels in a particular spot, they just start hauling trailers into place. In cases where people lose their homes, they might be able to arrange for a longer-run stay.
