Take a vehicle out of rotation, on purpose.
Too much demand and not enough cars, a driver on holiday, or any other reason — block availability for a period, on one vehicle or all of them.
This is about availability, not price
Blocked Seasons stops a vehicle from being bookable at all during that window. If what you actually want is to charge more on a specific date rather than block it, that's Special Dates instead — a different tool for a different job.
