Location: Booking > Special opening hours and notes

Go to Booking and select a day in the calendar at left side, then click on “Special opening hours and notes”.

Select “Special” and deselect the box of “Online booking”. It is now not possible to book online for this specific day. 

You can also add a note which will appear in online bookings, if you select the box “Show on online booking”.

As a result, it will not be possible to book online on the specific date and the note will show under the calendar.
