Michigan has a long history of STR's. All those lake cabins in the Northern part of the state have been rented out for a very long time. My father remembers summering there as a very young boy. They rented a cabin for two weeks every year. I can't imagine that the owners of those cabins would applaud being restricted.
Here in MA we have the same traditions with lakeside and oceanside cabins. Our governor is very reluctant to anger that constituency.
