How would I offer something like a promo code to friends and family who want to use our place? I am aware of the ability to offer a discount but I don't want to have to manually do it each time. So if I have ski patroller friends who want to stay at our place, I'd like them to be able to just book directly, and if I could give them a promo code, give them 30% off, or whatever amount.
I don't want a "promotion" because that's public and anyone can claim it. I just want a private promo code for this situation.
