I want to give a discount for a 2 week booking to encourage guests to book as opposed to a 1 week stay. The only facility there is to give to give a 1 week or more discount or specific weeks (dates)? ( to clarify i want people to book a 2 week stay instead of 1 week)
You can provide discount for any lenght of stay, but probably need to activate "professional tools" in your account before feature appears in section "discounts"
