The best way to do this is to create a Blocked Date or set a Stop Sell.
To set a Stop Sell:
Log in to app.zeevou.com and navigate to your Rates & Availability Calendar.
Drag and drop your desired date range on the specific property/unit.
In the pop-up, toggle Override Stop Sell to Prevent Bookings (or Allow Bookings if needed).
Click Save to apply the changes.
Note: Blaze and Dazzle users can also apply a Rate Rule with Stop Sell only for channels while keeping their website availability open.
