If you still have availability, but you want to limit what can be booked, then you can use a close restriction. With this restriction, you can close specific rates or rooms.
Option 1: Click on the rate - the pop up shows - click on the ''close'' tick-box
Option 2: Click on the open/close doors on top of the page, below the date indication. Don't forget to save!
Option 3: Click on the ''room options'' tick-box - door icons will show for each day and each room type - select the ones you want to close - click on the save button.
