Avoiding 1 or 2 night gaps in Short Term Rentals

[Blake Lawrence]

I have co-owned a property in Maui, while my partners did the management aspect. I am taking over the management and buying out their half.  In the past, when a vacationer has requested a stay and left a 1 or 2 day gap, my partner offered the additional day at half price but no one has ever taken that.  In some spots, I can afford it but January is a higher priced, very easily rented out time period and this person has requested a stay that leaves a single day on both sides empty.  My question with VRBO and AIRBNB is there a way to set it so they cannot leave a gap like this?   If not, what is the damage of rejecting their request? It is my understanding there is some metric that is determined by your acceptance rate and it may push your listing further down if you do not accept.
