Hi Camille,
I am assuming you are talking about the Grange Forest Retreat.
In order to take this off "Instant Book", click on you listing settings and on the left hand side, choose "Instant Book". You will then see where it says, "Instant Book is On". Beside that you will see a yellow lightning bolt. Click on the lightning bolt which should toggle off instant book.
Hope this helps Camille!
