Good question, @Quincy but all it does actually, is remind me that I still don't know the dark art of marketing! 😳
We (1) always adjust prices seasonally and (2) we'll add a promotional gift if we know of any events happening on certain dates in the area which we'll advertise on social media.
Other than that, we post on social media as often as possible to highlight features of the low season (fewer people, ideal time for quiet contemplation or reading under the covers).
Does it guarantee results? Hardly. But we keep hoping. 😅
Let's see if someone can tell me the secret here.
