OK so for seasonal workers you need "temporary" housing. I would think higher pay might help with high turnover if you mean more skilled workers and management.
I know St. Joe is building apartments with lower rents in Panama City Beach for workers. I'm not sure who else could afford that except maybe Sandestin or a group of restaurant owners?
A few other businesses have floated the idea. Most are talking about small groupings of apartments like 8-12 scattered across 3-4 buildings. The ultimate issue becomes where to build since NIMBY's will b**ch both about low income people living near them while also bitching that an empty restaurant has a two hour wait so the two servers that showed up don't kill themselves from exhaustion.
