As SkiAdcock says, it's not only from property to property but also can be different dates at the same property (depending on the situation).

I remember this year being surprised when my favorite Renaissance, which normally follows the "6 PM on day of arrival" rule, had a two-week rule for one period (which as I recall coincided with a big convention in town).

The key here is check cancellation policy every time, don’t get complaisant!
